Ask HN: Should .io domains still be avoided?

A few years ago pg wrote a great article on startup names: http://paulgraham.com/name.html

The resulting discussion was equally as informative: https://news.ycombinator.com/item?id=10030863

I'm wondering if this has changed at all. Are .io names to be avoided still? Have consumer/investor perception of them changed since?

This question comes as I brainstorm names for an upcoming project. The target demographic is generally a developer, and as such I picked up a relevant one word .io name. I am aware of available .com names which would suffice, but they're commonly two words and not as succinct. Would switching to a .com be advised?
