@meganmariehart the underlying protocol of Fediverse is not dependent on any tags. strictly saying it does not have tags at all. it works like email and delivery depends on user addresses ;like username+servername. if a connected user reposts or comments some post in Fediverse, there's a chance that his followers get a copy if the original post too, so posts spread across trhe different servers on Fediverse.
some platforms (like Mastodon) allow subscription to tags and some filtering on tags. others do not offer that features. but tags often may be used in seatch engines on servers and people may sort out messages with tags for easier search.
