It has often been said that it's a sign a forum has succeeded in its objective if a thread is discovered while looking something up.
This is why "shitposts" (and yes that's the real internet term for them, excuse my language) often have a handful of recurring critics, because they're not the kind of thing one would expect to cause someone to discover that forum via Google. Indeed, the words "I was looking up what it feels like to pet a human with nice soft fluffy fur and came across a throwaway forum post about it" are words we will probably never hear in the history of mankind, well, except for this sentence (nothing against them, just saying).
That said, when was the last time you actually were looking something up on Google (or DuckDuckGo, or Ecosia, or whatever you use, personally I lean towards Ecosia even if it's not as adequate to its promise as it seems) and you came across a thread in a forum and possibly discovered the forum's existence for the first time through the act of looking up said thing?
