Here's what diffs peeps like me (serverside) from peeps like you (ui). I
tend to focus on backend functionality, while spending very little time on
teh presentation layer. So my pages/sites generally look like chit, while
teh underlying app is a sight to behold (though some might argue a rather
ugly sight). Or put another way, I know just enuf about teh presentation
layer to be dan^H^H^H to get teh job done. But that's about it. ^_~
