Boksburg, Gauteng???

OK I added this new thing to my blog that tells me from where people are checking me out - at least that's what I though it did.  But I noticed this morning that someone checked me out from Boksburg, Gauteng.  huh?  I don't even know where that is, let alone someone who lives there!

Did I misunderstand what this widget thingy does or am I starting to get around?
