One of our esteemed members was having difficulty reading the small font on the new FaceBook App...and there's no way to adjust it. I suggested taking advantage of the iPad's accessibility option to overcome that. It will work with all iPad apps AFAIK. Here's how and a little demo...
First you need to enable screen zoom:
Settings > General > Accessibility > Zoom > Zoom On
Once enabled you can Zoom in by double-tapping with three fingers. Initially when you do that it'll just zoom in a little bit. To increase the zoom double tap with three fingers and then hold. Sliding your three fingers up will zoom in as far as you'd like and sliding them down will zoom out. To move around the page once you're zoomed in just tap and hold with three fingers and slide them around on the screen. To return the screen to normal double tap with three fingers.
Hope that helps folks that need to see things on a slightly grander scale!
