I like how you can choose to "like" videos, so you're not necessarily forced to put them in your Favorites if you want to save them. I don't like that you can't choose to show only some kinds of comments [-5 or higher, +5 or higher, etc;] or that you can't hide "objectionable" words [or can you? I haven't quite figured it out yet.] But I think I'll like it more once I get used to it.
Speaking of YouTube, are they doing site maintenance right now? When you mouse over the comments, it doesn't give you the option to thumbs up or down anymore. Edit: Never mind, it's back.
Doesn't it censor your comments now? Not that I'm an extremely profane person, but a few times when I'd try to submit a comment (that could maybe be construed as inappropriate), it said "posting error, try again".
So yeah, I kind of miss the old one. I don't mind the thumbs up/thumbs down feature though.
