IGN is so biased and full of childish Sony fans though so these votes mean nothing in my opinion.
Just a general question about these kind of observations, would that mean the consensus is NeoGAF, and now IGN, are vastly more populated with Sony fans? Certain Neowin members have been telling us a lot over the past months NeoGAF is a Sony site. If anyone wants to argue this line of thinking true, then where are the MS fans hiding? These are two massive gaming sites, 600k votes is by a polls standard not a drop in the ocean at all, in fact it's a massive number.
Any time someone says something like this I look at two factors
a) Is it a small site? If so, genuine chance it is vastly skewed one way or the other. Small time blogs, sites that cover news mostly from one company, etc, yeah sure, chances are there will be an overwhelming bias.
b) Is it a large site? If so, chances are you simply see vocal outbursts about ****ty decisions, and if your favourite company has just made a load, then that company will be getting blasted, end of. Chances are the actual balance of fans signed up to post/comment/vote is fairly equal, you simply see what you want to see.
And yeah staff members of large sites can have a huge bias, but this is a poll, not a staff editorial.
