If you are a developer that creates an app that is heavily text base you don't want to alienate over 200 million potential customers through the use of static text or limited enlargement of said text. The iPhone's Facebook, the BBC News and AP Mobile apps are prime examples of this shortsightedness. Facebook doesn't even attempt to give you a viable option to enlarge text in the app. Fortunately for Facebook users Facely is available in the app store and it handles text so much better. BBC News does give you an enlarge text button but they still don't enlarge the font enough to be truly effective. AP Mobile does a slightly better job at text enlargement but many will still find a magnifying glass, reading glasses or even Jeweler's lenses are their only option. One workaround to all of this is to copy paste the text to a word processing app and enlarging the text there. I will say that while the Craigslist and Craigslist Pro App's Listing's are small in Font size the details can be zoomed via gestures and works very well. Other developers could emulate this approach and make a potential 200 Million or more people say "Now that's a Site for sore eyes!".
