I'm not sure how much difference it would make to activate post counts in just that forum in particular. I don't pay attention to what forums have post count and what don't and I doubt new members would even think about the difference.
The getting staff and being noticed ideas make sense but they are down to the management.
The only thing I would alter about reputation (and I've said this time and time again) is the spread limit. As it stands, the reputation system does not provide a reliable indication of somebody's actual reputation around the forum (especially new members). This is because if a very good member regularly makes posts you think deserve positive reputation, there is no chance of you being able to award it for each of that person's good posts. Not to mention with the "dying community", there are even less opportunities to spread the rep to be allowed to rep the same person again.
This isn't an important point, but I was also wondering if more rep blocks should be added instead of stopping at the current maximum. It's just because earning rep blocks are the same as the excitement, if you like, of earning rep points and rep powers. But when I realised my rep blocks were already the same as people like Jake's, I was kind of like 'oh :/'. It's just with such a huge gap in rep/posts between people like me and people like Jake, you wouldn't expect the rep blocks to be the same, is all.
