I believe that in the early stages of learning anything, we have no framework with which to compare things. Thus, we may not even know what we are asking or know the significance of a particular comment. One word can totally change the meaning of a comment so when a newcomer to a hobby/sport asks a question they may not even understand others' questions/answers.
Yes, this. Also, sometimes if you are too new you don't even know how to ask the question/what to search for.
As an example, I posted a "should I secondary this?" thread very early on, despite their being a bazillion threads already debating that to death. In that particular case, I had not planned to secondary, but then saw something with the fermentation -- hell, I can't even remember what it was now -- that made me think that maybe it was important to do so with this batch.
So here's the thing: I wasn't looking for the pros vs. cons of a secondary (at the time I didn't even know there was such a debate, I just assumed based on the Papazian book that a secondary was recommended but usually not very important) so I didn't search for that. I said, "Ah hah, here is something unique to my situation that maybe makes it more important to secondary. Let me ask about that!"
Without further context, I didn't even know the import of what I was asking or that it was a more general and open-ended question than I had thought.
Another example, not homebrewing, just yesterday I bought parts to make a screen frame. Before I found the display for it, I didn't even know what I needed. All I knew was I had this screen door, but the screen and some "parts" for attaching it were missing. I couldn't even really ask an employee, cuz what would I even ask about -- "Uh, my screen door, there's some stuff that ain't in it." heh... So I wandered around, not even knowing what to search for or ask about. Couldn't even Google it! Finally, I found the right parts and immediately recognized them, and now I had the phrase "screen frame" in my vocabulary. From there it was quite easy to know what to look for/which questions to ask, etc.
But sometimes, you know so little you don't even know the right question to ask!
