One person's advantage is another's disadvantage. Lack of global (where global means all servers federated with your own) text search is a choice, not an unfortunate side-effect of federation. There are a lot of things I wouldn't post about if it were like Twitter and people could easily search (and follow) terms looking for people to harass.

Yeah I understand. The hard part for me with Mastodon is I have broad/diverse interests, but so many servers focus on specific topics. And I especially like FinTwit stuff, but the fediverse directories don't even have a "finance" or "investing" category.
