From Another Monkey:
By the way: SiteMeter is causing an error in all Blogspot blogs (and other sites) when you open them through Like, you can't open the sites. At all. I'm going in throug a SiteMeterectomy. Hopefully they will get this issue resolved pronto.This must be some new feature - it was only a problem with some sites last night, and now it seems universal. So they must have been rolling it out on a few servers last night, and then got them all by today.
