TWO ABSOLUTES of Web 2.0, according to Tantek Celik of Technorati:
- You control your own data. You should be able to move it around, mix and match data services.
- Data sits in open data formats and works with open protocols. It should be web-friendly, easily downloadable, and highly interoperable.
