Depends on what we’re talking about exactly. I’ve created twtxt (the format specification as well as the reference client) a few years back. Many other clients and compatible tools followed provided by other contributors. Sadly prologic chose to name his piece of software just "twtxt" as well, despite it deviating quite dramatically from the original idea.
Is there an issue that I call the backend (codename) the smae thing? @buckket I _assume_ yu're okay with this, although we haven't spoken much...
