Doesn't pretty much everything exist at this point already? I don't need any special top level domain.

Yeah, but unfortunately many names you want is taken. That's why the clearnet version of this site is ramble.pw, because it was available, and all the 'normal' TLDs were taken.

Most common word domains get squatted anyway. I've flipped many a domain in my time, and usually would just buy up things specific to a particular industry and then do nothing for a year or two then list them for sale. Buy a .com for $12, renew it once, got $24 tied into it total and then sell it for a few hundred to someone who will either actually use it or sit on it longer and re-sell it a year or two later for more.

Though my domain portfolio is empty nowadays, but when 'cloud' was the new buzzword for anything related to computing and hosting, boy did I make some extra coin.
