Ask HN: Better startup tld, .co or .io?

For anything techie, given that choice, I'd go with the .io version. It resonates with techies because of the overlap with the acronym for Input/Output. And it seems to be somewhat trendy to use .io for tech oriented sites.

FWIW, my newest SaaS offering is using a .io domain as well, so I am "putting my money where my mouth is" on this topic.

Domain names don't really matter. You just need to be easy to find on Google search.

You don't really believe this -- .com's obviously matter the most, but many good .coms are being squatted. If domain names (and extensions) didn't matter, then there wouldn't be such demand for some extensions and not others.

I would suggest going with .io as I've seen it used used online more often

You named your company before you acquired an appropriate domain name?

I haven't launched yet. And no, I have the .co and .io for a specific domain name, I'm just wondering what folks think seems better nowadays?
