OP: please don't say 'just get dot com'
All comments: 'just get dot com'
I had the same question and went with .co. I think .io is falling in popularity due to dns scandal. More and more people are using .dev now and .ai is also ok.
Problem with .co is people tend to assume it's a typo outside of tech (eg my bank).
A lot of startups I follow moved to .com after a few years so I assume there are more pain points that I haven't discovered yet.
My intuition for ranking is something like
.co
.dev
.ai
.io
But would love to see data on trends by company size etc if anyone has.
