I think it's fine the way it is, but making a separate subforum for suggestions doesn't sound like too bad of an idea. But shoving them all into one thread seems pretty stupid. I certainly refer people to Kaguya's list, but I also try to take into account what the person has already read and give them a couple of suggestions based on that. And then a discussion can start about those suggestions, so if multiple discussions about suggestions for multiple people start going on in a single thread it'll get really messy, really quickly.
