Don't take it from us, nor from
San'plex where I've just spotted this one. Oh no, take it from 2ch - the ultimate authority in anonymous studies of unquestionable shadiness, reaching mind-boggling complexity at times. And
this one makes no exception. By compiling all sorts of data based on user activity around 2ch, and factoring in each anime's
"Amazon rank, Mixi connections, blog hits and so on", a Top 10 for the Summer 2009 anime season has been determined.

Whether you like it or not, the top-most position is held by
Bakemonogatari, studio Shaft's adaptation of the supernatural comedy novels signed by NisiOisiN, which aired in Japan from July 3 until last Friday. As for the other titles that make up this definitive Top 10, well, here goes.
Tokyo Magnitude 8.0,
Umineko and
Canaan barely missed that list, coming in at numbers 11, 12 and 13 respectively.
The full study ranks a total of 34 titles, by the way. And I dare you decypher all those moonrunes!... While I go do my WoW dailies
and queue up some torrents.
