Backtype not collecting comments from Wordpress or Blogger

Backtype has great potential - but it doesn't seem to work with Wordpress or Blogger (the sites I comment on most). Is this just a problem with me, or is Backtype not configured to search for Wordpress/Blogger comments yet?

I've set up my Backtype profile following the FAQ instructions (claiming comments using the URL http://joelitobarski.com) and here's an example of a Wordpress post I've commented on, putting my website URL into the form:

http://stephenspillane.com/blog/index...

But it hasn't retrieved my comment. I've had the same problem with Blogger.

Is this a problem with me?

Many thanks,

Joe Litobarski
