Changes to the sidebar

Just  a quick note to say there's been a (not so) short column added for "past contributors" on the sidebar, which seemed an appropriate thing to do.  If by any chance we've missed someone or your name appears as other than you would prefer, please notify someone here immediately; thanks!  (A general question:  how accessible is this site to you?)

Also the blogroll has been updated.  See especially Meta-Philosophy, a new group project of John Protevi et al., including generous posts by John McCumber (whose work has probably been mentioned here more than once).
