Very nice feedback, thanks!. I know Tufte (here in HN there was a topic about his opinion on pie charts) but I've never read something from Stephen Few. I'll definitely check it out.
Regarding the building of some examples, yes, I've already made some of them for the news media job I have, but I'm doing a contract job for a real estate aggregator company (like trulia but from Argentina) and I'm interested in all things regarding public transport. So I think I'll explore these topics and see what sticks.
