Surprising, because I'd totally forgotten about it and really wanted to see what this was all about (after reading some of the comments here).

So I thought to myself 'ok, this once' knowing I'd be sticking my head out. It took me a minute or two to realize the cause and I thought that was a nice side-effect of solving this at the DNS layer, even when you're momentarily stupid this will still create enough of a barrier that you'll stop to think a bit longer.

I didn't know about the ghostery extension, so thanks to the person that posted that, that's another good solution.

FB has had its use for me (it found a bunch of long lost people), I haven't been back since.
