I really like the idea of Top 50s, as they are semi-good gauges of what the masses like and don’t like. MyFonts.com has a Top 50, which is pretty interesting to me. Some of my old time faves are there, including at Frutiger, Trade Gothic, DIN 1451, and Windsor, all of which I use all the time.
More importantly, one can see an obvious trend toward sans serif fonts throughout all media right now. The serif font (e.g. Times Roman) is still much easier as a text font (e.g. in a newspaper or a magazine) as has been proven by many studies on perception and reading, but for some reason, probably having to do with the technological flair and look of cleanliness, sans serif is everywhere these days.
