I agree with the other post here that it's important to genuinely care, so this Startup School, I visited justin.tv and scribd; incidentally, I danced at the hotel afterwards (coincidentally to a french song) because I was genuinely happy just to be in the area with smart people interested in new technology.

Your article is great because many young entrepreneurs aren't very social unless one is an alumni of the same college as the other, or have experience with the same technology. On the other hand, it is also a very efficient way of finding people who are exactly like oneself, in the case that a startup's business plan requires all members to look and act like clones of one another in order for it to succeed.
