Howdy all. I am a big Mastodon fan and have been trying to get my head around kbin/lemmy for the last couple of days. Decided to do some random interoperability cross-testing from around the Fediverse.

This is in no way definitive, this is mostly just me f’ing around, and I suspect some of this is federation lag too as they all have to populate one another. Servers used were retro.pizza (mastodon), fedia.io (kbin), and infosec.pub (lemmy):

From Mastodon -

• Can see kbin users and their post counts (but not their posts)
• Can see Lemmy users and some of their posts (but not any context, and also not reliably seeing their post counts)

From kbin -

• Can search for and see Mastodon users
• Can’t search for Lemmy users
• Can search for Lemmy posts/threads (and can see users through posts/threads/magazines/whatever they’re calling it) and fully interact with them

From Lemmy -

• Can search Mastodon users
• Can search kbin users (and see any comments they made, but only on Lemmy posts)
• Can search for kbin posts/threads but results are very hit and miss, cannot interact with them

Does this sound right to you? Do you have any tricks/tips for getting all these doodads and whatchamacallits to talk to one another better?
