I haven't read the whole thread so this could have been said before. I've belonged to several forums over the years and the early months follow the same pattern.
First few posts - very few replies if any. Thinking of giving up, they don't like me.
A few months later - starting to get the hang of what works on here. But still often the last post, no-one replies.
Years later, if you haven't given up, you get the idea of what the others want to talk about. It's not about you, it's about the general interest level of the topic.
News and Politics excluded.
And I avoid the relationship topics because I don't want to risk being identified.
