I've had better results searching through the instances themselves because Google doesn't always index the keywords on time. On caveat of this method is that if the instance doesn't have the syncing out the instance where the info is from being propagated, then this trick would not work

Wouldn't this just encourage SEO clickbaits more though? Also, a lot of these blogs can die over time, so it's also not the most reliable (like the owner can die or the domain providing service has expired or some shit). Also, how can this solve the problem of confabulated misconceptions (let's say that there are blogs that are feeding misinformation)? Without a moderating system, a comment section that can exist to engage and debunks those statements, and the upvote/downvote system... I think that it's hard to tell reliability of the information. Feel free to debunk my doubts though.
