Who says you can only get one? Don’t let the perfect be the enemy of the good; just get one of the fun ones you already came up with and in the future if you need a different one get that too. That’s been my approach, anyway.

The low hanging fruit will already be scooped up. You have to get creative with emphasis on it being pronounceable first and brevity second. I feel the biggest mistake that gets made is waiting for the perfect name and overlooking a good one.

the thing is that my imagination is known to usually spit out the best ideas when it's just too late.

The whole question is about 25 years late.

Domain names were cool then. Today nobody gives a http://da.mn/ anymore.

I’m gonna leave this here, go wild. Do note that most of big tech already bought their .sucks domains.

For my homelab, I used a constellation so I can name each of my server after a star in the constellation. It is on a generic domain extension.

If it is something long term, I’d generally opt for a more stable extension. I.e. vanilla .com/net/org; or cctld for an existing country that you have close ties with that’s not likely to go away anytime soon. It is extremely rare, but this way I’m not running the odd risk of the company behind those fun new extensions, or a country going away (see .yu, no pun intended).

Best ones I have are registered after either a random thought or a brainstorming session. For me pronounceable is a must (at least to some extent), short is strong second and funny is of course always nice, but not necessity. Including TLD is always nice, but unfortunately it's rather difficult at least with the TLD's I usually use.

I'll say that you probably want .com. Domain names that integrate the TLD are cute, but they can be problematic. Not everyone will pick up on the fact that it's supposed to be pronounced as one word. This leads into the fact that it can be hard to verbally convey this domain to other people. Very specific TLDs are also likely to have strict or unusual rules on their use that could get them revoked.

I have jumped domain names 4 times in the last year. Because I find a "cool new one"

But I've found the perfect one I believe now.

Simply found it by typing something "cool" and looking what tlds are available for that word or phrase

Which is the obvious method not really worth mentioning, but still I do.
