Meetup, one of the original social network/event organizing sites, has received new funding from Union Square Ventures. No other details were released, but USV’s Fred Wilson writes about it on his blog: “Meetup is a perfect investment for our firm because it’s a company we know well and a service we use all the time. We have been wanting to invest in Meetup for years but we never could find the right entry point that worked for us and the company and its founders.”

Meetup, founded in 2002 by Scott Heiferman, grew steadily during the last presidential elections, and has since become one of the major grassgroup groups and event organizing sites.
