Another thing I was thinking as I was re-reading this thread is that for some VCs the fact that you can game your GH star count might in fact read as a positive signal. It shows you're willing able to play a kind of vicious PR game to get popularity.
Again, VCs not interested in pure technical excellence or geek "cred". They likely want you if you're the kind of person who can stand in front of a room and puff yourself up and make yourself look more important than you are, and frankly "acquiring" GH stars might just be part of that.
