Depends.
If you think what's typed is representative, then you're almost certainly badly wrong. A lot of what's typed is typed by people with extreme views ( compared to most of the fanbase ), and those people are very vocal, to the point of being gobby. A current example is the "will you go to a game with Allardyce still in charge" kind of thread. If you took any notice of what you read in that sort of thread then you'd expect Goodison to be half empty, but, strangely enough, it isn't.
But, GOT has a heck of a lot of members who don't type much, if at all, but when there's a poll posted which attracts interest, it could quite easily get 1000's of votes. The results of those polls will be far more representative of what the fan base really thinks, than any of the polarised views typed in the same thread.
