Urgent Evoke

A crash course in changing the world.

Evoke, a week to make an upgrade in the world of webapps is one thing, but to remove a major feature of the site for a week is crazy! Evoke users, tell me if I'm wrong, but this site is full of some of the most high-energy people I've seen anywhere....you could be losing all kinds of amazing people because they are losing a key way for people to connect to open-minded leaders!

Bring back the leaders tab, even if it's "compromised"!

* UPDATE* Evoke: Could you tell us how the usage patterns changed once you took down the leaderboard? That wouldd make a great blog post for one of the developers or creators of the site :)



*UPDATE # 2* How about adding a most Leading Blogs as well when it comes back.
I think having a most viewed stat might be more accurate in tracking "popularity" than the votes as well, just because not everyone is familiar with the vote system. I imagine what ends up happening is when a blog is voted on a lot, it's because the people familiar with the system have viewed it a lot. So in some sense you are getting a "Most Popular" by a certain demographic of users here (ones that know how to use it). You could even get the compliment to that and count how many people saw the blog and didn't vote. This might give you the "Most Popular by New Users".

Just some ideas

You could have another categorization called "New". This is how you would categorize things when you have no data on them. This is a common technique in feature analysis in pattern recognition and other fields. In pattern recognition, what I'm suggesting is called "classification" based on the features defined here as "Powers".

The scores are more for you, than for anyone else, so if you are a generalist and are too busy doing 20 different things and don't have time to contribute to this game, then your starting score is going to be just right. (But you won't make any connections, and you won't be considered for funding/support for your ideas, and you won't get that coveted certification prize from the World Bank as a social innovator!) So the way you choose to participate, and how much, is up to you, based on your goals. How do you want to be perceived?

Haha, I still haven't bothered to read about any of the rewards or anything for fear that it will turn me into a conspiracy theorist!

Go for it! I have studied Bayesian Networks though, and can tell you the most important thing about pattern recognition in my opinion is KEEP IT SIMPLE. More than any other field I've studied, this is an imporant thing to remember. Most of the time, the most robust pattern recognition algorithms will only take into account at most 3 features. The trick is finding the most useful 3 features. Anything more than that introduces 2 major problems. The first is called noise. This is where your results actually become less accurate because you are now trying to add in features which may only have a loose correlation with the problem. The second problem is that of complexity in finding a best fit and analyzing incoming data. Trying to solve a formula with more than 3 variables gets very difficult, and even if you come up with a form that fits what you're seeing, it's likely that making the evaluation against that fit will be too costly in performance for the algorithm to be useful. Anyways, now that I've started, I'll write a blog about this later. Good luck though Panamericana, and let me know if you want to talk about any of this.

Nicholas, how about these for your three powers as your Bayesian features:

Good at making stuff that works
Good at collaborating with others
Good at coming up with new ideas

I don't know much about Bayesian networks, other than I'm pretty sure they are awesome when done right. :-) So even if Panamericana was kidding, it might still be a good idea...

Let´s step back a little. Do we even need to keep track of who is participating more? We need to figure out a way to encourage the people that is contributing less to participate more. Truth is we need to avoid what happens in most systems- Pareto´s Principle seems to emerge even in nature http://en.wikipedia.org/wiki/Pareto_principle
Comment by Nicholas Nagao on March 25, 2010 at 6:34pm
Turil, thanks for picking up the conversation! What you're describing is actually Cla****, not features. Let me explain, a feature is something like a person's PowerVote score, or other things we can MEASURE. So a score easy pretty easy to measure in at least 1 way, as you can just use the score as the measurement. A class would be the different "categories" you are going to classify things into. So in your example some cla**** might be:

Inventor (good at making stuff work)
Engineer (good at implementing stuff)
Oraganizer (good at collaborating with people)
Visionary (good at coming up with new ideas)

The idea of Bayesian networks tries to take this basic idea and expand it into a larger "network" of classifiers. This is actually why I said you should keep it simple because in my opinion the additional complexity of a network approach is self-defeating. Anyways, I am happy to continue this discussion and will be sure to start a new blog about this so we can all talk in more detail!

I'd suggest you mine comments for such scoring, as well. I know I, for one, won't re-post a comment idea I had to my blog, since I was working off of another persons' post, but it's certainly a measure of a person's usefulness.
Comment by Nicholas Nagao on March 25, 2010 at 6:36pm
By the way, I'm not at all suggesting this is a good way to do a leaderboard, in fact it's way too complicated for this...I also believe in keeping it simple when looking for the solution. I'm just discussing in case people are interested in Classifiers and Pattern Recognition.
Comment by Nicholas Nagao on March 25, 2010 at 6:37pm
Thomas, I agree with you! You are describing "Relevance" in the web space, which is an idea I've been trying to spread here to help people have their blogs get more views.

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

The meal

It is 7'oclock, I was late home from work due to an assignment that i wanted to get ahead on. By the time I get home I am feeling extremley tired and I cannot be bothered to make a proper meal. I walk to the fridge and open it to see what there is for me to eat. All of the out of date foodstuffs have been automaticaly thrown away by the fridge, they will be recycled tomorrow as animal feed or something. I see i have organic local eggs and some local cheese. Foods are vacc** sealded for easy…See More

Future

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
