I'm getting mightily annoyed with Facebook's lack of care about Pages. When I first heard about them, I thought they were a great idea, but it turns out there's absolutely no vetting for a page, and anyone can masquerade as an official company even though they're just a fan. This means companies and advertisers who wish to operate on Facebook are being discouraged to do so. I looked at 43 facebook pages with over 10,000 fans and deemed that 27 of them were certainly fake, and only 5 appeared to be set up by the game publisher!
Interesting stuff, but it remains to be seen if Facebook can develop chat enough to kill off other chat clients. At the moment people will surely be sticking to their guns and staying with messenger and aim, especially with integration. But eventually, won't people want all of their media easily managed in one place?
