Being “popular” on the forums isn’t about having the most posts - realistically, anyone could have the most posts if they continuously spammed threads.
The important thing in my opinion, is being involved in the community, contributing detailed, engaging and helpful posts where possible, and if you have something you’d like to say, but feel it’s too short or doesn’t give anything back to the community that they can really engage in, you can post a “status update” on your profile!
As an avid forums user, to me seeing spammed threads personally takes the appeal away from the forums, and makes it look quite untidy.
Thanks for coming to my TED talk!
