Reallyfuckingcool.net or .org available, same for getsurfing, learnsurfing and justhangingout. With all these domains there’s no real point unless you are getting a dictionary word or a specific name, imho.
I have seen some TLDs owned by a company and didn't even bother to set a redirect.
My anecdote is that the ICANN annual fee ($25k) is easily covered by these obligatory registrations and the premium domains. The cost of running nameservers aren't that high. NS1 has an offering, but it's impossible to find their pricing for anything.
