I agree with this and sometimes people may post the same question because they want to have their "own discussion" and they deserve that. They also want to feel heard and recognized, they deserve that. They want to feel important, not annoying because they didn't search the topic, they deserve that. Etc..... I believe not making someone feel annoying, or like is courtesy to them.
You could make the space bar the entire welcoming page, it wouldn't change a thing. I don't think merging is the way to go either, it makes the OP feel grouped into one big pool of the same issue and we all have our unique experience with that. But if making it bigger would make you feel better I say go for it, just don't get even more frustrated when you don't get a major change in behavior. Heck, God can't even get his kids to listen LOL
