I just gave you the delicious listings for J/W fic, so I can't vouch for all of the fic there. I'm not big into that fandom, so I don't really know a lot about what's great and not, but things you see linked by a lot of people generally indicates that at least many people liked it. Del.icio.us is a great resource for finding specific kinds of fic out there, especially small fandoms.

And despite my distraction with other projects at the moment, there will definitely be more Guy/Kakashi in the future, in the very least in the form of more DnaLS omake that I have planned.
