I almost exclusively use my phone, and this forum is very hard to read. The zoom feature on my Android cuts off usernames when it makes text of posts big enough to read, and in typing a reply, it's basically impossible to read what you're writing -- if you want to review more than 4 words at a time.
I tried the WAP2 thing yesterday after reading this thread, and it does make text more legible, but navigation of the site is very difficult. I almost always read from the "Recent Unread Topics" page, which either doesn't exist or loads improperly in this mode (it said there were no unread topics, and when I switched modes, there were at least 15).
