Although, lezzie porn is OK. In fact it's to be encouraged.

But seriously...

I agree with what the others said: simplicity and lack of gimicky stuff. Easy navigation, perhaps repeating the links on the page so if you're at the top or bottom you still see the links.

Nothing pisses me off more than pages that take ages to load, admitedly our company net is a bit slow, but you can't expect everyone to have super-duper bandwidth.

Make sure you have a Contact Us or Feedback area.

I agree you don't want too deep a structure, but if your site is about (say) products, don't have everything on one page for each product- have a few pages per product covering stuff like an Intro on one page, heavy techie stuff on another, specification list on another, environmental on another... but all with easy obvious links.

Make sure your pages all adhere to some kind of theme- your company colour scheme for example.

Assume users may come to any of your pages from outside your site, not just via your homepage, so they should be able to see where they're at in your site overall and always be able to get to your home and other major sections from any page.
