Ahhh I was sort of under the assumption that you could pretty much pick whatever you wanted. But if it's bound to usernames, then that makes sense.
Still, it would be cool if on my jesta account I could add a record for stats.steem with the appropriate DNS :)
Yep, but sadly that would be quite difficult to do without some sort-of side chain. If you had the account "stats" or "steemstats" you get a cool domain though :)
Luckily I have steemstats, stats is by a random user though.
Let the username squatting begin! lol
