Starcrossed (for DW crossovers) now has entries that link to over 56 fandoms crossed with DW, all of them gen or PG. And I've got a whole lot more to add soon.
Stats (because the things Wordpress tells you fascinates me...)
Top stories read from the site:
1. The Dalek Invasion of Discworld by TigerKat (11 hits)
2. All Time Lords Great and Small by AussieDalek (9 hits)
3. This Is How The Universe Ends by googlebrat (another Discworld cross; 9 hits)
Top posts (although people can click straight to the links and read the posts fully without clicking on them, so these have a lot less hits):
1. Stargate (14 hits)
2. All Creatures Great and Small (13 hits)
3. Star Trek (9 hits)
(For ages All Creatures was the top post, which I thought was great, but Stargate remains just ahead)

They Do Things Differently There is a site for historical DW fan fic recs. These are much rarer creatures. However it now has links to 36 stories.
Top links:
1. The Winter of Our Discontent by lareinenoir and rosamund (3)
2. Red October by Various (3)
3. Regency Romance by AND (2)
Top Posts:
1. Alternative History: Twentieth Century (Protect and Survive by JJPOR) (12 hits)
2. 1917: Russian Revolution (Red October; 11 hits)
3. 1817: Switzerland (A Vampyre More Accursed by jinxed_wood; 7 hits)
Most days they get at least a couple visitors each. Starcrossed often more, although one day in September for no apparant reason the historical one got 28 hits. I've no idea why. Then it went back to 0-2 visits per day. (None of the hits are me, btw).Anyway, they're both becoming reasonable collections of links and recs, which is nice, and hopefully helpful for people.
