Yep, there are some bizarre things going on and at the moment I do not like it.
Just why, in Google's infinite wisdom, would typing in my company name show the result in the titlebar as example.us? Absolutely nothing else at all except the correct meta description.
We do own the example.us, it is on a url forward to the .com from our registrar, however that is all which is displayed however if I perform a keyword1keyword2 search then it comes up with the correct titlebar.
Incidentally I have this happening across several TLD and ccTLD sites.
