Was this written at a time when there was no Discord web interface? I use a FOSS Discord channel in the browser so surely it's just as accessible as any other text website?

The bigger limitation seems to be that it's not visible without signing up, nor Googleable. But I think that helps people be more relaxed and free. Sometimes I see a bit of swearing and generally coarse language which is completely fine and expected for passionate people, but might be dampened if it was more transparent.
