Not very, currently. It's a hard problem, because it's basically a marketplace. You need both the projects and the maintainers for it to work, and it's a notoriously hard chicken-and-egg problem to solve.
The way I wanted to solve it is to have as many projects as possible in the Shelter, so that when you came across a project that was abandoned that you were interested in, you could simply become a maintainer and take it over. Unfortunately, projects don't have much of an incentive to be added to CS when the maintainers aren't there, so the solution hasn't worked that well.
