There was a great defcon talk about this. Basically using unicode and registering domain names with a bit flip resulted in results. Like email at Microsoft and some other major companies.

I think the title was dns squatting but can't find it at the moment

That's the one, thanks for finding it. It really is fascinating

That was actually the inspiration for my experiment with this in school, and I also setup one or two domains to catch bit flips but never got any hits. It's a complete myth as far as I have been able to tell (research tells me otherwise by using huge setups, and there are a few commenters here that seem to have first-hand experience, some seeming more trustworthy than others, but clearly not a majority of people). I get that it's (obviously) more than a myth, but I'm not sure it deserves the goo-goo eyes that it seems to trigger with many engineers, either. It's a neat feature slightly above the gimmick status but gets way more attention.
