Many of our employees were there already, and we've admittedly all become fans of Twitter.
Twitter is a micro-publishing platform (posts limited to 140 characters) which combines blogs, instant messaging and a social network. It's been kept purposefully simple, but has grown rapidly through offering a popular API allowing people to build upon the network and technology.
We're keeping it relaxed and friendly, sign up and follow along. You can find us @ http://twitter.com/plankdesign.
