Twittering from now on whenever I have the time to. If you are following the right people on Twitter it can get quite interesting. Another cool thing is #tweetcoding, set up by Grant Skinner.
If you twitter something you only have 140 characters for your message. Tweetcoding is a AS3 contest where you take 140 chars of setup code and integrate your own 140 chars of code. The whole thing is then compiled with Flash CS4 (Strict Mode off). You can also see my first real entry here.
