No Pay - But a Great Opportunity

My writing buddy and blog reader, Heather Larson spotted this gem:

"No pay but great nationwide exposure opportunity. Let me know if you're interested in having your name on the homepage of a nationwide site. Information will only be forwarded to serious inquiries. Thanks :)"

This is just one of those things that make you go hmmm.....

First of all, aren't all websites "nationwide," so if I were going to write for my own enjoyment or exposure, why wouldn't I just buy a domain name and put a site up and advertise it? Why let someone else make ad revenue on my sweat?
