I have used a lot of fonts over the years (many of them non-Roman), but I know nothing about legibility except a few anecdotes. One such anecdote: I was trying to read a sign the other day that said either "68" or "88"--the two digits were almost touching, and it was extremely hard to read, as both the top left of the '6' and the '8' were rounded. I notice that the Globotipo font has the top left as an almost straight diagonal line. I like that. BTW, there was no need for the two digits to be so close together--there was plenty of space on both sides.
