As some of you know, I make web sites for a living. I think it's sufficiently fun to be worth waiting for, at least once. It's cute and it downloads fast and also presents a menu at the bottom for users surfing with images off. The OnMouseOver nav frame on the Well Tempered site with the circular buttons would be a bad idea for homemade sites because most DIY webmasters have never heard of anti-aliasing. You creative designers have let loose a tacky epidemic of enormous proportions.
People copy and paste crap all over their websites without a clue as to how it works.
Javascript is buggy between browsers. I spent a good hour today hunting a javscript bug which appears only in NS Navagator 4.6 which doesn't seem to allow 2 scripts which use the built-in date object to execute on the same page. So, even if your script seems to work with your browser, you won't know for sure that it will work with all browsers. I can't wait to move all my pages to the new server with PHP compiled into the Apache module. Server-side processing is the best way to go.
