Unless you don't know what Web 2.0 is (in which case you should not be reading this blog), Twitter has become quite a popular service. Either by the people using it, by the talks by the watercooler or by the constant press about its downtime, Twitter is another way for people to kill time and broadcast their lifes.
In one sentence, Twitter is a like blogging, but you have just 140 characters to write each post and people can "follow" you (and you can "follow" them).
Quite a few of Seattle 2.0 entrepreneurs are Twittering nowadays. It's hard to define the content of those "tweets" into a single category, but they go from the personal ("I'm ordering dinner"), to the venting off ("I just came out of a stressful meeting"), to the question format ("Where can I find ...").
If you just want to know what the top 10 most followed Seattle founders, CEOs and CTOs are twittering about, check the list below.
