So I've had this instance of Takahē @takahe running for a bit over a week now, and after a bit of hit-and-miss with the setup at first, it seems to be seeing posts with no issues. However, there are a few things which prevent me from switching from my current account @osma to it as a daily driver..
1. The current version of Takahē does not migrate follow graph from Mastodon yet. :)
2. Based on symptoms I'm seeing in federation, it seems the Fediverse at large doesn't really like the server domain (social.fishpool.org) and the identity domain (fishpool.org) being different.
3. Something about media propagation is off, but I can't tell what the issue is.

The other lightweight alternative, Wildebeest, appears to have the same limitations.

@takahe sorry, didn't notice your question before! Pixelfed is one of the cases where I noticed issues, and I'm still not sure this identity propagates correctly elsewhere either. When viewed from Mastodon, it does seem to be working as expected though.

I'll be upgrading once you're ready with 0.8.0. What's the remaining roadmap for account migration and auto-notifying followers of the new address?
