All I have to say is, the testimonials are awesome.
I really love Twitter.
Twitter is the first thing on the web that I've been excited about in ages.
It's one of the fastest-growing phenomena on the Internet.
And yeah, it's like someone made a site based off of one of Facebook's/MySpace's most annoying features (status updates). I don't think I've ever put a serious status on FB, like, "heh, doing homework ttyl."
