After posting my review of iWeb I discovered that it totally screwed up my link to my blog. Specifically a link to http://homepage.mac.com/gregjsmith caused a 404 page, where as http://homepage.mac.com/gregjsmith.index.html still works. This was annoying enough that I just didn't want to deal with it.

I was finally able to fix this by going into the .mac homepage settings, deleting all my pages listed there and create a new one. That reset my index.html page. I then republished my index.html page and now I'm back and working.
