I didn’t quite understand what you mean by…

“it’s compatibility with other Fediverse software is currently very limited”

I think the interaction between Lemmy and other Fediverse accounts is going quite well. Especially when posts are written from Mastodon etc. to a Lemmy community, things have improved a lot recently (e.g. when hashtags or links are in the headline)

The long term viability given the core developers is a question I’ve definitely pondered. The low priority for moderator features is especially concerning. Didn’t realize they also were petty.

I’ll be keeping an eye on Sublinks.
