I got this in the mail today. Jacob Nielsen is an expert on web usability and has this great article on diversity of media on the Web.

As an aside on useabilty. I, as a good blogger, try to include a lot of links. I used to often put a link on a word like “this” or “here”. This has always been bad form, but I didn’t really notice it until I started using all caps for links. Then I found you couldn’t scan the page and see where the links went. You had to read the whole sentence with the link in it. So now I like to a phrase and not a link word.
