@maia Nothing really :) MastoArt refers to 'mastodon' rather than the whole fediverse (Mastodon is the name of the software but there are other softwares people can install to run an instance like ours, so 'fediart or just 'art' are more all-encompassing in that sense, but people using non-mastodon instances will still see content tagged with MastoArt so it doesn't limit its reach or anything
