Yeah, not quite. Anime threads in general (whether they be show specific, or what have you) certainly make sense because they're actual about something, such as a specific show or news about a studio.
Recommendation threads are just what happens when people believe they don't have access to enough information about a subject. They signify some kind of problem.
In reality, of course, people could just search the archives for one of the many recommendation threads, or the anime advice threads, or just ask in here. Time period specific threads, and top anime threads, are also good resources. Yet people still create more of those threads. I'm sure that part of the reason why such threads are created is because people aren't aware of 1) this thread in community and 2) the rich history of anime threads available in the archive.
Moreover, even when we had a thread in the OT, usually near the top of the list of threads, we still got recommendation threads. Just not as many we do now.
