In a lot of ways it is better, supports hashtags, has full activitypub support (not just the group support) which allows following users, and allows boosting.

Though it also has severe drawbacks like a lack of MD support (glitch-soc has it but normal Mastodon doesn't), doesn't allow arbitrary link attachments like lemmy, and does not have good community/group view or threaded comments, though these last two are mainly front-end issues.

Lemmy doesn't have follow functions for users, only for the community actors. Lemmy users can't follow individual accounts. Though threads users can follow them, and also follow communities just like Mastodon users can. Also they can post to communities and reply to posts and comments in them the same as Mastodon users can.

Title Section

Post body

Hashtags (optional, can also be in body)

Community Actor handle mention i.e. @community@reddthat.com

I am absolutely not in favor of federating with threads, beyond the EEE scares and corporate abuse they also have a huge problem with moderating properly and have large amounts of trolls and transphobic content. Facebook has a very bad track record in general with moderation and has allowed this type of content to thrive on their other platforms in the past, threads doesn't seem to be an exception.

These servers also block threads as well. Basically all the most popular instances except lemmy.world are blocking threads.
