I'm been having a couple of problems with my ClustrMap recently - the numbers seem to have got stuck and are not reporting correctly. I find you do tend to stare at numbers as you come up to a big one - and this blog went past the 50,000 mark about 10 days ago according to Statcounter.
The nice people at ClustrMaps (Hi CJ!) are trying to sort out the problem out right now. So while I'm waiting for the fix I've just made the map invisible and it'll be back as soon as it's all sorted. And I now know a new bit of code thanks to the people at ClustrMaps!
