You should register a somewhat short & clear domain and run a public instance! Or is it up to someone else to provide that service? BTW: Someone registered twtxt.org, maybe that's a good place to provide such a service there.
Currently, < http://htwtxt.plomlompom.com/ > (HTTP-only so far, will probably look closer into the whole certificate business after the weekend) is my attempt at a public instance: sign-up is open (for now), and I don't plan on eradicating the feeds regularly as I do with < http://test.plomlompom.com:8000 >. But I'm also a bit hesitant to promote this instance aggressively at this early stage of development. I'm happy about anyone testing it by registering, or even by setting up their own instance.
