Just out of curiosity...why aren't gifs allowed in the H2H contest?
I hope that it's a matter of integrity. In a judged competition that's taken seriously, it's essential to compare apples to apples.
It simply makes no sense to judge a moving image against a still one, much like it doesn't make sense to judge a story against a song.
Personally, I believe the original spirit of this site was to create the best possible still image by manipulating the daily source - even if it meant using Gimp or Corel (as some still do).
However, since it's called Photoshopcontest, many believe it's about showcasing one's skills in Photoshop, no matter what advances Adobe comes out with.
Back when I took voting results more personally, there was a contest where I placed third, about 20 votes behind a gif, and it really chipped away at my enthusiasm here.

Now, when I vote for gifs, I try to vote for the ones that tell a story even as a freeze frame.
I still think gifs should be in a separate category, but since I started viewing contests as more fun than serious competition, these things just don't bother me as much anymore.
