Tweet Trumps -- which was created by Tom Scott and Dom Hodgson over the course of 24 hours at European developer conference Warblecamp -- generates a deck of online trading cards culled from your mutual Twitter followers (people who follow you back). Basically, you're given a card with a collection of stats about a certain follower -- number of tweets, grammar quality, number of followers, etc -- and then you must guess in which category said person "trumps" another one of your followers.
Here, I was given a card featuring my friend Sammy Davis, who is an awesome vintage clothing seller. Since Sammy D. is rather loquacious, I guessed that she tweets more than my average follower. As you can see, I was correct; she beat out Mashable Features Editor Matt Silverman handily.
The game still has a few bugs -- it was created in one day -- and only works for unprotected accounts and people with more than 20 mutual followers, but it's still a pretty stellar way to kill your morning. Also, it's a hell of a lot cheaper than online poker. Amirite?
