Side Bar Tidy Up

I've just had nother of my periodic clean ups of the side bar menu and removed a number of dead links. Caratacus has gone as have Jon Swift, Larry Ayers, Mingshi's Kendo and Green Ink. All have stopped blogging, apparently. The Postman has gone private. Guy Fawkes has taken himself off to another site which I can't be bothered to find. Wonkette has gone too wacky since Ana Marie Cox left. Iraq War News seems a little out of date. Lab Rat has closed his site and is now writing for Nature magazine and Tangled Bank has petered out. A few others are looking precarious but I'll leave them alone for now. I'll be happy to reinstate anyone who reappears or feels that I have been unjust.
