I have some bookmarked, but definitely not a nice list like that one, and not as many. Do you have more like these? I love to indulge into these for a few minutes a day, during commuting on the subway. I am always wondering if its because it somehow gives instant gratification into that desire to do something meaningful with the time with very little effort, ie that something new was learned (and then usually as instantly as learned forgotten :) )
