Right now /r/ is pretty much shit and nobody uses it for anything other than "who is this naked woman" and "can you please photoshop boobs on my facebook friend" and that kind of thing. This is a problem because, for instance, people are frequently told that /r/ is the proper venue for certain kinds of posts (such as recommendation threads on /a/).

If you look at /r/ right now and sort it by "number of replies" you see that there are only six threads that have more than ten replies. This kind of clutter isn't really necessary and defeats the purpose of /r/.

My suggestion: Make single, recurring threads for the most common post topics. Make a single "photoshop request thread" that can be sustained, which will probably have better results because the people who are actually contributing photoshops will only have to go in a single place. Make a single "porn identification thread" and use that for all the posts asking "moar of her?" Then you will have the whole rest of the board completely free of clutter which will allow other "request" threads to spend more time visible on the board, and therefore increase the quality of answers.
