Most of us have heard of John Gabriel's Greater Internet F******d Theory (link slightly NSFW). I would wager that the majority of gamers even believe it to be true.
But it has never truly been proven, or conclusively demonstrated. So for that alone, I am looking forward to Blizzard's plan to integrate RealId with the WoW forums. Maybe it will turn out to be a good idea, maybe it will turn out to be a bad idea. But at least we'll know. There's something to be said for actual experimentation, rather than just armchair theorycrafting.
Heck, maybe the *real* problems with RealId on the forums will turn out to be completely different than anything that has been thought of.
Sometimes I think our society spends too much time worrying over potential outcomes, and not enough time actually doing things. Not to say that we shouldn't think ahead, but there is a balance, and right now I think we've swung too far to the worrying side.
I think that, on the whole, RealId integration with the forums will work out well. I think the official forums will become much more usable. Many people, both good and bad, will migrate to other forums like Tankspot, and that might pump up some of the non-official sites. But I could be wrong. Maybe there will be many negative consequences.
In some ways, this is probably a tipping point for gaming companies and the internet. If the forums calm down and Blizzard does not lose customers, every gaming company that can will follow their lead. If Blizzard does end up losing money, then we'll probably never hear these schemes again.
Though, kind of honestly, it's going to be weird seeing Greg Street post instead of Ghostcrawler.
