There's a button ^ ^ ^ up there somewhere that allows you to change the size of the font.
Personally I think it's a good idea. You may not be aware of it, but your eyesight starts to deteriorate from around the age of 40, so having something in a larger font for those who are, presumably, older posters can only be a good thing.
It's the bane of my life working in market research, having to research packaging designed by 12 year olds who insist on designing pack copy in a tiny font and in the same colour, just a lighter shade, than the darker pack. Ensures that copy is impossible to read for older shoppers.
