4. Why do ranks even matter, it's not like it makes a difference?
This is one question I found myself answering earlier and the real short of it is this. Rightly or wrongly people can make money by posting in this forum, as they increase ranks, their earning potential increases. The community is incentivised to contribute and help one another by such things as signature campaigns. If we end up in a scenario whereby the elite remain elite and those at the bottom remain at the bottom then it will only promote discontent within the forum. It is vital for the forums success that there is always a progression and a constant stream of new members. If these new members feel that the same opportunities are not afforded to them then they won't stick around.
Agree with you, those members here who have been here for a long time and got ranked-up not for quality post but for their length of time in this forum. Whether we like it or not, those guys have alt account.
