I am all for the anonymous posting of entries. People are more willing to give a look/read according to prompts and not names on that basis. I know that I am guilty of doing it myself i.e. reading that writer's story or worse refusing to even give a certain artist/writer a try due to past experiences. It being anonymous would ensure a more fair distribution of reader/viewers and a fairer evaluation of the entry.
As for reducing the games to one per year and combining art and fic: I am not sure as to how I feel about that, mainly because I like being able to do both.
Giving out prizes to commenters: I am not sure how one would judge that. It screems wank-potential to me.
