I have been struggling to find time and energy to blog lately and in one area in particular I have been especially lax - the comments. I have received many excellent comments even in this slow summer of blogging and have responded to almost none. I shall try and rectify this - even if very late in the game - in the next few days.
Anyway, thanks for your patience and I apologize for the slow blogging this summer. I have been making considerable progress on my field experiment for this blog, I shall update that soon.
