Yeah, I've noticed this quite a lot too, especially in communities for making online friends. Posts from girls saying they're looking for friends often get tons of upvotes and comments, while similar posts from guys tend to get almost no attention.
What's interesting is that I've noticed this in myself too. For some reason, whenever I see a post from a girl looking for friends, it catches my attention more, and I find that a bit strange even about myself.
Maybe it has something to do with the gender ratio of Reddit users. But I also wonder if there's something deeper behind it. Could it be influenced by the way our society and culture have shaped us, or perhaps even by some of our natural human tendencies?
Edit: Just like how, among countless flowers, we tend to notice the brightest one
