Great Post! It's funny you mentioned the Startup Weekend because I just came from one in Durham, NC and instead of paying to be apart of the conference; I decided to volunteer. Based on my experience, I feel that volunteering at those types of events is the best way to meet people because your not burdened with staying in one place and working on one idea.
Definitely agree. I am actually wearing my Startup Weekend jacket right now (I help with NYC) and I got started volunteering. There is a limit on this, but if there is room, I would highly recommend getting involved with this organization.
