That's 2 reviews for that company's wallpapering jobs, but there are also 71 reviews for their interior painting, 72 reviews for their exterior painting, 7 reviews for their wallpaper removal, and so on.

For the interior painting, there are three reviews from February of 2010 alone, so there is some recent information.

Angie's list isn't perfect by any means, but I do think it's possible to get useful information out of them.
