One of the reasons I don't bother with memes any more is because I'd rather have a prompt to respond to rather than a blank post with only an icon and username. Not knowing much about the character necessitates wiki-reading, then poking around the character's journal to see if anything's in there to showcase the player's writing skills, and then writing a starter if the above steps prove interesting.

I suppose it's a good way to prevent more cross-canon threads, but that seems counter-intuitive to the open-ended format of memes. I'm not sure where posting a blank starter began, but it's pretty backwards from normal RP experiences outside of DWRP memes.
