I joined Twitter.
Having stayed off of Facebook - I know, how is that even possible - and MySpace and all the other social sites so far, I decided that being in the industry I should give at least one a try.
It has been just over a month and after getting over my initial qualms, I have to say that I think I like it. At first, I felt egotistical posting 140 character snippets about what I was doing right now. Like anyone really cares. But then it was pointed out by @thefrontlawn that blogs could be considered just as narcissistic.
What I appreciate most is the developer community. For example, I made one small post about working on a Filemaker plug-in and almost instantly had followers asking for details or offering assistance. It's this sort of online camaraderie that could actually increase my productivity.
