We have a page listed as an expert site. It is our "Links" page, and just points to useful sites having the same general theme as ours. Hopefully, it's of more than dubious quality, but at the same time, the only reason I can see that it was included is that there are a lot of themed outgoing links with a paragraph of text describing each destination site, sort of like the ODP.
Teoma may need to implement a PageRank-like algorithm to judge the quality of these expert sites in order to make these citations more useful.
Personally, I'm just grateful to be included (free) and to have all those long-dead URLs removed from their index!
