@OwlZaku there are two main, cultural things for Mastodon to keep in mind, which you may not have seen just yet.
1) there's a strong emphasis on adding alt-tags to images for accessibility (this does slow things down, but it's part of the 'we'd like to keep everyone in the loop' kinda vibe)
2) content warnings are encouraged, esp. for things like USPol
Other than that, very happy to see you, esp. the gunpla stuff
