Social networking for freelancers

Another great post from web worker daily discussing the value of social networking for Entreprenuers and freelancers, and highlighting a new network called LimeExchange.

Here is an excerpt:

"A few weeks ago, LimeExchange launched its online outsourcing marketplace to the world. The service is essentially a social network for freelancers, service providers and entrepreneurs that helps service providers matchmake themselves to buyers looking to outsource activities within those service categories.
