YouTube: no change. GoogleVideo: foul-mouthed

One article says:

You have to click to enable the comments on Google Video, and you may want to keep some mouthwash handy to gargle with when you're done. On-topic comments are rare, with most folks preferring to post crass racist and/or political items, as others contribute only to pimp their own uploads.

It also says:

Then you have the overt trampling of intellectual capital. Just check out the "Top 100" list, and you'll find clips from networks like ESPN and Discovery Channel. They aren't just being used without permission. No, it gets worse. Third-party sites are overlaying their own website addresses as watermarks on videos that they clearly don't own. It's pretty disgraceful to see that Google is letting that kind of thievery shoot up in popularity.

Another article points out that copyright policies at YouTube have not changed since Google purchased the site:

YouTube hasn't changed at all, only people's perceptions or expectations of it. The company states in its user agreement that uploading copyrighted material is illegal, and a similar warning appears before you upload a clip. But of course, fewer than 1% of its users upload anything. No wonder they don't know.
