Even better - you can see the whole thread from both #lemmy and from #Mastodon . However, you only see the conversation, not upvotes/downvotes in mastodon, while you see votes too in Lemmy.
Edit: I tried to not tag @firefox this time to see if my reply showed up on Lemmy. It didn't.
Tagging so the Lemmy thread also shows the reply and pictures.
Edit++: so retroactive tagging doesn't work ā¹ļø...nvm, it just took a bit of time to update!
Not quite. An upvote on Lemmy is a favorite on mastodon. However, all posts on Lemmy look like they are a "boost" by the community when viewing from mastodon.
