kbin can interact with mastodon freely, so if that’s something you want to be able to do easily, you might want to switch over from lemmy.
I was thinking you can probably open the user’s profile on lemmy and reply to the post from there, but testing that didn’t seem to work. I assume that’s just federation taking a while though, so I’d say try it anyway. Searching for @name@usersmastodoninstance
I mean. I don’t see why it wouldn’t work.
What do you mean with broken? Seems to be working fine for me.
If you mean it opens an error page, you probably left the thread open for too long. Upvoting and boosting does bring me to an error page if I do it after walking away from my pc and coming back. But a refresh fixes that.
