i thought this would be a good idea for a twitter app - something like you tweet your goal then each day you tweet what you did towards it and if you didn't it'd auto tweet that you broke the chain. idea being you don't want your friends to know you broke it. there's obvious flaws but if someone is interested in it, i have the domain twitchain.com and won't get around to making this anytime soon so if you can have it if you want to build something like this.
