Most of the "regulars" started off as semi-clueless newbies, were impressed by the depth of knowledge and helpfulness of the existing regulars, and sought to emulate them (with varying degrees of success).
If you build it, they will come.
N.B. One of the major differences between PePiPoo and FTLA is that PePiPoo started off as a speed camera, etc. site, with the parking forums added originally as somewhere for the idiots who insisted on asking for advice on parking tickets on a speed camera forum to post that wasn't the speed camera active cases forum.
This site has been heavily driven from an active decriminalized council penalties page, so there will always be a degree of apples and oranges.
