I should share an odd obsession I have. I read blogs about currency. By this I mean about national currency. Spend some time at the Engraveyard won't you?
I have been on dates with typographers recently. Which is a strange thing to think about in itself. Before August I could honestly say I never even met a typographer, but now I have gone on dates with 3. If you have never thought about the ways of letters, I strongly suggest you look around you at this very moment and so that thing.
