I hate mobile and I hate the move away from traditional forum software. Every site I've ever seen that focuses on mobile ends us being squished in the middle of the screen with huge white space on both sides. I use a laptop with a 17" screen sitting on a fixed platform and a remote keyboard and mouse. I can't even see these sites on a 4" screen. You have to consider that many users on this type of site may be older or have vision issue because of the work they do. We don't want to have to hold a device in one hand 6 inches from our face and try to type with a pointy stick.
Even those that have to use cell phone based web services can tether to a device with a larger screen.
The ONLY time I have ever even tried to use a mobile device for a board like this was during an extended ISP outage and it was not a pleasant experience, even with a BT keyboard.
Maybe you could tell us some of these other sites that have been assimilated so we could see what's been done?
