Twitter might be competing with blogging or with Facebook. However, I wonder if it is competing with mailing list.
Indeed. Isn't Twitter mainly one-two-many outlet? Is anybody out there doing wiki-related research and annoucing it/discussing it via Twitter?
Facebooks is more plausible, but due to restriction on who can join it, I don't think it works. I don't even think there is a serious/active Wikipedian group at Fbook (I joined some few months ago pro forma, and wasn't terribly impressed), and I am pretty sure there is, again, no Wikipedia research being discussed there (barring researchers occasional random comments, directed more to friends than to other researchers).
Blogs, on the other hand, are much more of a serious competition (nudge, Erik :)
