Does anyone write or prompt for one? I been playing around in one for the Hobbit and it has helped me deal with some writer's block. I think they're a great tool to use. You can find requests for anything and everything, from total smut to complete silliness. Also being able to post anon takes the terror out of putting something out there, at least for me it does.
I had done one for Pokemon before and a few for Homestuck (though so far haven't done smut fills yet, lol). They're fun to write indeed. I still check around Homestuck's kink meme if a prompt grabs me.
Got sucked back into the StarTrek meme for a while, that meme is so massive you can get lost for days. I'm having a minor problem, I claimed a prompt in the Hobbit meme and forgot to click anon. Now I'm struck with writer anxiety.
