I am not, it seems, the first person to ask this. Or even the ten-thousandth person to ask it, looking at the github issues list. And it looks like there isn't really a good solution. Some instances show their local timeline on their /about page (tabletop.social doesn't; I don't know whether that's admin choice or not); you can't follow a whole timeline from another instance (many bugs requesting this have been closed). The answer is: have two accounts. I am sad about this answer, but OK, fine.
Well, now I have two accounts. So I'm likely to be talking about roleplaying stuff more as https://tabletop.social/@sil, I imagine, unless I get really annoyed with this two-accounts thing and abandon that.
@sil It is the admin's choice as to whether they show the local timeline. It seems a little unwelcoming to hide it for a community instance like the one you're talking about - perhaps message the admin to turn it on?
