IMO that's one of the sticking points with a lot of newer forum systems. A more casual / light techie / designer type has a lot more trouble installing these systems without help, the right server setup, etc. That other new one using Ruby on Rails is similar with the increased level of difficulty.
Car guy sites and a lot of the "common man" catered forums will have a lot harder time adopting to the newer standards until the install process for self-hosted becomes easier..
Not a knock on you guys at all. This isn't even official release stuff, etc.. just an opinion from a guy who is 100% proficient on the look and design side and 25% proficient on the hardcore coding and server side of things
