Not a huge problem: it existed for 9 years and no one is talking about it.

If it becomes popular, I’m pronouncing it “twixt”, even if it’s wrong.

The upvotes on the pronunciation in the sibling comments should be considered legally binding and will be the authoritative pronunciation. Upvote carefully.

I think I'd pronounce it as, Twit-ext?

Not a Welsh speaker, I see

Intuitively, I read it as "tweetext"

Talk? You write about it, on a (mechanical) keyboard.

It kind of sounds like twitter extension. This is what i thought of it as when i first seen it. This can be very confusing.

Most of the community call it Yarn. They use twtxt as the protocol name - and it isn't like HTTP is one vowel.

I suppose that if one were motivated, one would run a https://github.com/plomlompom/htwtxt service and then point the audience to it.

Not clear that the juice would be worth the squeeze over, e.g. Mastadon.

There is a long history of confusing or weird project names in computing like sqlite, gif, Splunk, Hadoop, Coq, MongoDB (from humongous apparently), yacc, C, R, and X (the window manager; not a lang or the social media site).

As its name says, "double u" is not just one but two vowels. (-:

twit-text is how I would pronounce it.
