There was some positive feedback on the previous question, so let's give it a try.
- Journal Club is intended to be a whole day meeting (with 3 meet-up sessions to seed the discussion) on chat where we discuss some paper and its theoretical/practical surroundings.
- The paper must be OpenAccess or a (p)reprint suggested previously on a meta thread like this one and selected in voting. It should be both interesting and understandable (at least in idea) for a broader audience.
- We (mods) will try to invite the author(s).
So, please suggest papers (each in one answer) and/or upvote propositions you like. The deadline for voting is 1.28.2011 23:59UTC and the first approximation of the JC itself is 2.4.2011.
