I'm kind of proud of myself when it comes to web design. I've never fallen victim to the common mistakes of making web pages. I've never used frames. Frames are evil; I've never used the <font> tag (it should go without saying that <font> sucks big time); I've never used tables for layout. My navigation bar is in fact a Done. I've never tried to hide my source code. Hiding your source is stupid. I forgot to mention that I actually used to abuse <table>, but I like to call it a table of links. I mean to make this into a list of links with the upcoming redesign, though.<blockquote> just for its left margin on the news items. Not anymore, of course.
In addition to not doing the stuff above, I write clean and structured code which is (in theory) highly accessible. But you already know that.
