I found the mobile experience to be very poor. The ads take up the whole page of my smartphone !!!. It's really impractical browsing threads with multiple pages because I constantly have to wait for the gigantic ads to load up (which also eat up data in KiloBytes) and scroll and scroll. Are there any plans to make a barebones version of the forums or at least one optimized for handsets? Because I check the forums constantly on my mobile when I'm at work, and I'm sure many others do aswell. I don't know how complex the coding is to do this, but I visit a lot of forums on my smartphone without downloading any specific "Apps" and they seem to automatically optimize for my phone. It shouldn't matter whether someone has an Iphone, Android, Blackberry or other. Also it shouldnt be necessary to "sign in" and specify the "style chooser" as "Mobile" at the bottom left pull down menu of the site. A mobile browser should be automatically recognized for usability.
Also I know advertising is important to maintain the site, but it appears rather clunky on the main site. Eats up too much header space in my opinion. Also echoing everyone else's thoughts on font colour.
Besides that, keep up the good work, I know it's a work in progress! And thanks for the hardwork and serving a great purpose over the years.
