It's quite sad. The comments below (at the time of posting - I expect there will be a lot more comments in the next few hours) make interesting reading too. It does seem that in some areas of science (lab focussed) supply at post doc level is now far outstripping demand in the higher levels. Something to think about maybe for people considering an academic science career?
Some of the issues mentioned by the anonymous author are issues I recognise from experience (my own and that of family/friends) in other disciplines though. It's clearly not just science that has problems...
