Frankly I just use the website installed as a web app. I’m quite happy with it. I lost a bit on the ux of thread closing but I get access to the emoji picker from my instance which is invaluable.

Wtf lmao, glad for you it’s a former roommate.

Never used pleroma, but poa.st is a neonazi/fascist instance. Their instance data was leaked a few years ago and just looking at the DMs leaked and the wordcloud it was even more vile than their usual racist posting.

Basically your post is already “posted” there. Anyone with a mastodon account on an instance that federates can see it. They could either paste on their mastodon search interface the url to this post and see it appear as a mastodon message. They could then reply on mastodon and it would show for you here on your lemmy instance.

They could also follow your account on mastodon or a community just as if you were a mastodon user and then see your posts on their timeline.

I have no idea for your first question.

Yes I’m sure but it depends on your theme. For example, Shydactyl theme must be customized to display favicons

Tridactyl? I prefer it to vimium due to native messaging support
