Don't assume to have known much just because you have rank up, but exercise patience to learn well and be more useful to the forum, this will also help you have more quality post than chasing cloud.
This is not a rule but a timely advice to newbie who wants to keep their posting reputation in good standard.
One meaningful post is better than 15 to 20 post that are low in quality just to fulfill signature requirements.
You are right, but most people don't get carried away as you may think, they might just think that they have to post to meetup their signature requirements which is why some have to respond to some threads they have no idea about, but it is still part of learning because we learn every day.
Ranking up is hard because to get merits in this forum these days is very difficult, that is why some of the newbies that ranked up to member rank will be aiming to use their account for signature campaign and keep posting so that they can keep earning and ranking up at the same time.
Quality posters always standout despite the number of comments that has already been made so far in the thread, therefore, it is good to be a quality poster by all means.
