I make some useless posts, and when I saw this thread, I decided not to post in it after thinking for a quite bit.
I looked back at some of my first posts, and as I started to try to use correct grammar, I got use to how the forum works, and started to try to make useless posts, but have an answer with them.
Example:
I said “lol…” to Samad’s funny post, but answered the question of the thread.
I try to do that whenever I can. If everyone always tried to do this, I think “useless posts” are ok, as long as they have an answer along with them.
