Subscribe to a post: just mention the bot in the comments.
Not a huge fan of the noise this adds to the threads. Would be nice if Lemmy frontends could provide better ways to interact with bots. For example custom buttons that would PM the bot with the appropriate message to trigger the action.
I might be able to set something up with the InstanceAssistant browser extension. It would be nice to have it in the main UI, but this could help temporarily.
I'd second the worry about the bot comments and bot-summoning comments becoming noise, I remember all the "remind me" comments on reddit clogging up comment feeds!
That's good, though I'd imagine people would still rather not read 100 bot-summoning comments on a popular thread. Any way to activate the bot via PM too? Or maybe by sharing somehow?
