Actually, we read most of the pitches that come into AngelList (there's an up-front algorithmic filter for junk). There are other investors who browse the incoming firehose as well. If we think something is interesting / likely to be a good match, we email it to investors who follow those markets and locations. If the company gets interest, we broaden the send. Investors follow / take intros as they're interested. Keep in mind that 95%+ of businesses are not fundable by early-stage tech-focused Angels. AngelList is not a circular-reasoning walled garden. Most of the value that we bring investors is surfacing them deals outside of their social networks, and most of the value that we bring startups is finding them investors outside of their social networks. If we didn't do that, we would fail.

It's very much like a dating site. We can't let all of the guys contact all of the girls whenever and however they want. But matches are made all the same.
