Ok, this is probably old news, but FaceBook now allows you to set your own url, e.g. my facebook profile used to be here:
Now it is here:
This is very nice, I like. Why they didn’t do such an obvious feature before is a bit of a mystery really. However, getting a custom Facebook url (or vanity url as it’s sometimes called) is now easy, you just go here: http://www.facebook.com/username/
WATCH IT THOUGH: it’s a one time deal. You can’t change your mind and you can’t undo it, so make sure you’re happy with what you chose, and make sure you don’t mistype it!!
