So lately, I've been playing a lot of games set in the social networking stratosphere. I just added the app, Scrabulous, which is the Scrabble game designed digitally. Prior to this, I've never played Scrabble before, so I'm learning the strategy of placing the most valued letters that pays off double or triple.
Then, Ilteris and Nick just got me into this game called Meta-Markets. The point of this game is to gain the market by trading shares and IPOs. Nick is so nerdy that he even created a script so you can aggregate the delicious links that follow the IPO rules (will publish this link soon, so stay tuned).
How to play:
1) You select a market (Flickr, Delicious, Facebook, etc.)
2) You buy low, sell high.
3) You can offer IPOs but there are certain restrictions (e.g. bookmarks that you post first on delicious that have to be posted at least by 10 other people)
4) You could set the price you want to sell them at, and set the amount you want to sell as well
It's kind of a strange market (social capital as a commodity), but interesting approach to learning economics. It really forces you to be proactive with posting news of photos first, and then sharing them, which promotes it virally. If you collaborate with enough investors, you could raise the prices (insider trading). The publishing markets will get a hoot.
As you can see Ilteris and Nick (relevante) are doing very well. They rank in the top 10 in 3 or the positive categories. This is a true time-sucker, and they're servers are really slow, but I think worth the wait. Designed by MIT students.
