Well, the Bing Webmaster tools are working again, or now, depending on your viewpoint. For the longest time I found that it generated an error when I tried to add a site listing.
So I get in, and download a list of backlinks to my site (it's my sig, don't think I can post URLs in posts yet). Very surprised, I found an entry in the backlinks from DMOZ.org - which I thought was very rare, but then I noticed the link is not in a "regular" area of DMOZ that I'm familiar with... perhaps it's in an editor's queue?
