Speaking for myself, my issues with GWE were the tone and attitudes of certain people during the process, and less the results. There were aspects of the results that I didn't care for personally, or that I felt ran really counter to the discussion threads in some ways, but that's the byproduct of having an open process. There isn't much you can do about it.
Had GME been hosted on PWO I probably would have taken part despite my visceral hatred for ranking matches out of a sense of obligation. With it housed elsewhere it's unlikely I'll participate. Honestly with matches I'm likely to just throw a list together in five minutes today and send it in, then spend any time mulling anything over and that kind of runs counter to the spirit of it anyhow. That said, I hope people enjoy the process and have fun with it.
