Socialtext raises a series A round as Ross explains, with existing investors (Joi Ito, Reid Hoffman, Mark Pincus and Freedom Technology Ventures) -- and new investors (Jun Makihara and Omidyar Network):

This is a major milestone for Socialtext, positioning us to build upon our market leadership and fulfill a mission we began in 2002. When Pete, Adina, Ed and I founded Socialtext we saw an opportunity to build a great company that did great things for its customers as well as society. The epiphany was that this could be done with simple easy to use tools and we could foster a way of working openly that builds trust between users.

It's particularly interesting that Ross says he met Pierre Omidyar through blogging, rather than the traditional VC meet-and-greet route.
