alt Hacker NewsHandy tip: all two-letter TLDs are country code TLDs. Doesn't matter if they're trendy in website names (.nu, .cc, .io, .co, .it, .at, .cx, youtu.be and so on)
In fact, here we have the ma.tt website, where the ".tt" is Trinidad and Tobago. Is Matt Mullenweg from Trinidad? No!
Though not all country codes point to a country. See .eu, .ac .su as different examples of stuff that breaks the rules.
