Yes because almost everyone agrees it should be raised (Greg and Luke excepted, though they agree it should be raised eventually). The poll didn't ask about raising to 20MB.
The devil is in the details, with no details, its all angels.
I suppose I would vote "NO" to most any change without knowing the details, but not "NO" to change itself. I think Gavin is getting closer and closer to something that will make sense. He is down to 8mb now, changed at a particular future block?
