How about a little more clarity on what "sucks," since the above doesn't approach constructive criticism.
1. It's decidedly unpreposessing. (That means ugly, if you didn't know.)
2. The PM system (or whatever it's properly called) is a pain in the patootie.
3. You can't post YouTube videos. (Or if you can, I haven't figured out how)
4. It sticks all these funky characters where punctuation ought to be, making stuff awfully hard to read. (Especially older posts)
5. The quantity and quality of the smileys is severely lacking. STL (powered by Invision/Zeta) has a lot more smileys, and they're way better too. (Jespah knows what i'm talking about. Just ask her.)
Of course this is all just my opinion.
