The Summer, 2009 issue of Cinema Journal features a section on fandom in general and vidding in particular edited by TWC's Kristina Busse and featuring a number of members of TWC's editorial board. (Yes, that's a shot from Lim's "Us" on the cover!) The issue is currently being mailed to subscribers, but eventually will be online at JStor and available through academic search engines in libraries and such.
