Technically, we didn't try, someone else tried and we let them do it.
We are currently in the process of working on an app and improving mobile a ton. Download chrome for your iphone and it works a little bit better, but we're slowly updating every piece of the site so that it's optimized for mobile. Until this summer, we were still using the same base code from Harvey when he created the site in 1999, so needless to say we were a bit behind and we're doing our best to catch up with the mobile craze.
