Actually, I think a lot of the issues with forums have to do with people vastly underestimating their complexities, and overestimating the importance of storage space on modern systems.

As an example, suppose I have a forum that's centered on vB. Take a guess how long that takes to setup, not counting WAMP/LAMP config here.
Now, suppose that I have to have each upload handled on a separate basis, duplicates included.
That's going to be Complexity + Storage, where End Value is determined by Productivity.
Money is variable, but it helps with Time and Effort, which are roughly equal to Productivity.

Bottomline:
I think what happens is that a large number of people don't see the End Value in an inherently niche market, so they never give it a chance to truly thrive.

EDIT:
Now, all that being said, if Lorekeep wants to dedicate site space to that particular interest, that's his call to make.
I just hope that people don't deride him for "wasting" storage space that they don't pay to use in the first place, and oftentimes never do (myself included).
