As I heard it first time, I did 30 sec research and found out:
Twitter is a social networking and micro-blogging service that enables its users to send and read other users' updates known as tweets. Tweets are text-based posts of up to 140 bytes in length.
So yeah a blog where you say what are you doing, hmm well I guess it would be fun to read what active people would do, but me? nah, so I don't twitter.
On the other hand, guys, let's make an Argo twitter community?
