if you're suddenly having trouble with blogger, no "edit" links when you view your page although you're logged in, check your settings if you're using Google Chrome. Not sure what I did, but whatever it was, it fixed it. Sorry if this doesn't help!
LOL... just sayin', it's not Blogger, it's Chrome. I enabled a couple things in the cookies section. Now I'm able to "like" stories from CNN directly to Facebook again, which I'd also lost the ability to.
