I went to royalmail.co.uk. It redirected me to royalmail.com.
What's up with that? I would've thought that they'd register a .uk domain! They're a UK company, for goodness' sake, aren't they?
For me, this is on a level with the fact that the US Army public-facing domain is goarmy.com and not army.mil. (Unless I've misunderstood something.)
Treating top-level domains as meaningless is somehow irking for me. (I also find it weird if German companies get a .com domain, especially local/regional ones such as Hamburger Hochbahn AG—though to their credit, they're also hochbahn.de now.)
