Found this cool article about writing for the web. Has great pointers and descriptions on what to do and not to do. I have not seen an article that has covered as much information all in one document. It is almost like they were reading my mind. Imagine it is a government site, maybe my phone is tapped. j/k
Seeing as how I work on an intranet support team, you can imagine how many times I want to edit someone's content on their site.
Anyway - if you're interested take a look Writing for the Web.
Enjoy :)
