Granted there are sites to find a co-founder but why doesn't YCombinator have a link like "TeamUp" where people post what they're ideas are, what they can do etc. It'll be helpful in forming a team, especially if you know that they're already a YCombinator Junkie so there's already some sort of a connection.<p>There are other entrepreneur networks but it seems like everyone is scattered among the networks.
We've found that startups are much more likely to succeed when the founders have known one another for a while. If we set up something like this, we'd be implicitly encouraging people to go down a path we know tends to result in failure.
