Thanks. I’d not want to add a 3rd thing, RSS, into the mix, so following from Mastodon might be a workaround. Ideally, I would “follow” in Lemmy itself!

True, I am looking for “get threads boosted by this account”. If Mastodon did threads well, I would have stayed on it. I wouldn’t care for it at all if I could also “follow” accounts on Lemmy (and the accounts that matter were on Lemmy).
