As we start the year of 'social aggregation and syndication' (as 2009 has already been dubbed) Web 2.0 gurus Seth Godin and Brian Solis are talking up how your ‘digital identity' defines who you are in the online world.

Godin asserts that two major factors influence the way we perceive people through their online incarnations:

• On the web, people are judged almost entirely by their actions - usually by what they write.
• Online interactions are largely expected to be intentional. On purpose. Planned. People assume you did stuff for a reason.
