I met with David Beisel of Masthead Venture Partners yesterday.  David writes the Genuine VC blog, which you can find in our Blogroll.  David has been running the Boston Web Innovators Group networking events for people interested in internet and mobile innovation.  I missed the last one in January, but David is targeting mid-March for the next one. 

David has been focused on Web 2.0 type companies at Masthead.  One of the demos he featured in January was Sconex, a high-school focused social networking site which has had explosive growth.  I’m a big fan of the new wave of social networking and sharing/tagging sites.  You can also read David’s recent blog entry about Vertical Social Networks.

I’ve tried out LinkedIn, Facebook, Friendster, but the one I use regularly is HeyLetsGo, which is more event-focused.  I don’t know anyone in Facebook and Friendster, since the target audience is not my age group.  However, HeyLetsGo was started by some friends of mine, Rebecca Xiong and Roy Rodenstein, and I know a lot of people in that network.

On the sharing/tagging sites, I have yet to try out Flikr but recently tried YouTube.  I use a desktop client for tagging my own photos and movies (Adobe Photoshop Elements), so haven’t felt too compelled to try the online sites yet.  I’ll talk more about these sites in the future.
