This (should) be a quick post, for those of you who haven't seen there is a new website that I think you should all go an look at:
it is a lobbying group that aims to improve the way libel cases are dealt with in the UK, have a read about on it have a look here for Ben Goldacre's info on it (he's one of the founders).
If you live in the UK and in any way care about science this is important, if you live elsewhere and care about science its important. If you don't care about science you should and then this is important.
Essentially our current libel laws are crap. The cost of libel in the UK is about 170 times that of mainland Europe, and the burden of proof is upon the defendant: ie when someone sues you for libel you are guilty until proven innocent.
For better (and probably correct) arguments about why you should give a fig about libel laws look around on the libel reform page as well as Ben Goldacre's blog or Jack of Kent's blog or just read up on what's happening to Simon Singh.
Please look at it and come to your own decision; this is important.
