i imagine a fedisearch engine will come out that can search lemmy, kbin, mastodon, etc. efficiently; so instead of googling “how to x site:reddit.com”, we’ll just fedisearch “how to x”
in fact, i’m pretty sure i already found one but it wasn’t very good, and i’ve forgotten it’s name
as a way to search inside communities: https://www.search-lemmy.com/ is in early development but it works surprisingly well usually
