Seems like the main kinds of people who would go to a VC review site are people who either a) tried to get funding and didn't, and want to rant about it, or b) people who don't know anyone, and therefore are not going to get personal introductions, and therefore are not going to get funding.
I don't know anything about it, I've only read blogs and YC News and Founders at Work, but that's my impression.
