But is there some way to make that mastodon.social address actually present itself as "@jwz@jwz.org" and make that be my canonical address? I would like that address to be the one that people find and see. Without running my own full Mastodon instance, I mean.
- Update: No.
My PHP redirector is here, it's pretty simple.
Some searching suggests that "host-meta" and "nodeinfo" URLs might also be involved, but I don't know what those do and it seems to be working without those.
Update: Alas, as noted above, it turns out that doing this is pointless, as you can't make "@jwz@jwz.org" be the thing that anyone ever actually sees, unless you run your whole own instance, which takes a colossal amount of effort and resources.
