Matt on Web 2.0

As someone who has been around the web since the early days, I appreciated this tweet from Matt Mullenweg. Matt says many people think Web 2.0 was defined by social media platforms like Facebook when in fact "platforms like WordPress, Odeo, Six Apart [Movable Type and Typepad], Flickr, Technorati, and had open data and interoperated." There are some interesting comments from that thread and others who are retweeting it.
