I think it's a very interesting idea, but I definitely see your problem of how to get initial content. I think a good niche would be programmers of a certain language, maybe ruby, javascript (or even just jQuery). Try to hire a couple of the more popular bloggers in the space to start seeding it with data and promoting it some and I think it would take off. If I was looking at a certain rails plugin it would be really interesting to see a list of links to tutorials for that plugin as well as some competing plugins that I should checkout.
