I’ll let you know. I’m thinking for photos:
Croissant —> Mastodon —> Micro.blog
My main hangup before was that posts would be linked to the Mastodon source. So when I inevitably change instances, or a personal instance crashes, it breaks the links.
No longer an issue, and so long as quality remains good, I think it will be fine. One big downside might be alt text. I don’t know if that transfers over.
