If you're an independent or freelance creative in photography, design, art, music, web design or any similar endeavor you'll appreciate clientsfromhell.net and its true (as far as I can tell!) stories of, well, clients from hell. I teach in this field and actually use the clientsfrom hell.net site to show my students what kind of stunts clients and employers can pull. It's entertainment and education all in one package.
A couple of minor caveats:
It's best to browse clientsfromhell.net with the JavaScript turned OFF in your browser to avoid the highly intrusive pop-ups constantly asking you to register at the site or sign up for something.
Avoid the comments section at all costs. There's an awful lot of superiority complex in there.
Just read the main posts and skip the comments and you'll enjoy Clients from Hell. At least in small doses: Even though it's funny, you'll find the sad reality of freelancing a little depressing if you overindulge!
