I discovered a great, practical guide to typography, and now I can’t stop noticing how important fonts and text sizing really are. The author sells some high-end fonts (starting at $100+), but he also recommends several excellent free alternatives.
What’s really interesting is his business model: he claims to make over $10,000 a year from this free book. That’s pretty cool, I didn’t think that was possible, especially when even paid books often struggle to cover their costs.
