And is this really a problem? If someone comes to the forum just for the sake of bounty and is happy with it, then maybe he doesn't need any ranks?

If someone does not read and study what the forum can give, then what is the point of him being here at all? Well, such users do not have new ranks, so there's nothing wrong with that. But there are also those who visit the forum for years, read, but do not write anything much, and also don't grow in ranks. And that's okay too.

It is strange to consider ranks in themselves as some important goal. You can both get something valuable and interesting on the forum without any ranks, or get some ranks, but achieve less than someone who reads even without registering. It is not the ranks themselves that are valuable, but what you achieve. It seems so.
