Had a quick snout around. Arguably beats the likes of http://www.emulator-zone.com/

These sites are one of the main reason people still use old out of date emulators. So instead of just complaining about these bad sites, we should try to make something to counter them.
The wiki is currently only maintained by a few people, so it reflects their biases. The more people, the more viewpoints, the better. I think the wiki is a good start.
