Why doesn't my blog posts get displayed by my username?

I added the feed url in the options and it it appeared for like 10 seconds after I first added feed and hasn't come back since. I tried using variations of hte feed url to no avail. Please advise.

Thanks!

 

Whats the url? put it exactly like it looks..

And Currently Blogger, Movable Type, WordPress and MySpace blogs are all that is supported.

Try adding it again then check it after a few posts some times it takes awhile to show up.

 

The url is: http://www.theartofbuzz.com/feed/rss/

Its been in there for days - I also tried other variations of the url too.
