AskReddit, being the best comparison I can make, had a lot of questions with an established theme. Usually along the lines of asking Redditors what they thought or experienced around some topic.
AskLemmy on the other hand never really established a particular culture, and not everyone here necessarily came from Reddit. So instead, it's become more of a community for general, genuine questions, rather than one seeking subjective experience or thoughts.
One of my favorite search ads that appeared in the mid 2000s happened when I was bored. I searched "grandpa" without any context just to see what would come up, because I really was that bored. One of the ads that appeared was one of those where they just shove your search in the title verbatim so someone not paying attention might think it was what they wanted.
It said something like "Looking for grandpa? Find great deals here!" I don't remember exactly what the second part said, but the "Looking for grandpa?" part made me bust out laughing. I then started searching other random stuff to try and get something equally stupid, but it didn't capture me quite the same way. Either way, my boredom was alleviated.
