First of all, this interesting podcast with twitter co-founder Evan Williams (and co-founder of Blogger.com) made me sign up.
Things I learned:
#1: Twitter is so freakin’ easy. It just answers one simple question: What are you doing?
#2: Twitter is like mini-blogging. Because its so easy that I can do it whereever I am via SMS, I twitter more often than I write blog posts (= more content for my blog via the twitter-widget)
#3: Evan does what he is passionate about and EATS ITS OWN DOGFOOD (= one important success factor of both twitter and blogger.com)
#4: I am definitely no early adopter (since I started blogging in august 2006 and twittering in april 2007). I have to be convinced and see real value before I try something new. Thats an interesting personal insight :-).
Example of twitter power-usage:
Robert Scoble asked his 2500+ twitter-friends what tools he should install on his new MacBookPro. The 2500+ friends received an SMS/IM/RSS-alert with this question and sent Robert dozens of tips in just a couple of minutes. Thats value!
PS: I’m sure you already saw my twitter-widget in my sidebar :-).
