I don't think "Google Maps" is a "Must-Know" site. It isn't very good. Weathernetwork is good, but only for north america... http://www.newegg.com/ and http://www.ncix.com/ maybe good sites. But only if you are interested in. The same thing for the online auction sites: If you like it, they may be good. If you don't like online auctions of corse not! The most tools of http://www.bravenet.com/ can you have better at msn.com without extreme ads. You may like it, okay but since this is only money making I don't call it "cool". https://www.penny-arcade.com/ is a freaky site too... All in all I think EVERYBODY has its OWN Top List. because everybody like (or is interested) in other things. Greets, Matti-Koopa
