They should increase it even more. It's not just elderly people who have poor eyesight or don't like straining to read things on a computer screen. Even if they made it 18pt, how much of your screen would it really occupy? Not much, and the usability benefits are huge. I seriously will leave websites for using small fonts. If I click a HN link and the font size seems below 10pt, I'll probably just leave. I've seen websites linked on here with fonts around 6 or 7pt. That's insane. No one can read that as comfortably as they could at 12pt.
For elderly users increasing the font size is not much help. The problem is with focus. The lens hardens with age and nearby objects appear out of focus. So 12pt and 24pt type will both be out focus:<p><a href="http://www.scientificamerican.com/article.cfm?id=why-does-eyesight-deterio" rel="nofollow">http://www.scientificamerican.com/article.cfm?id=why-does-ey...</a><p>"When the lens loses its pliability it also loses its ability to focus over a wide range of distances. A hardened lens becomes more fixed on distant objects and cannot focus as well on nearby objects or vice versa."
