They are not the usual suspects: They include survivors like Restaurant.com, which most people -- including, at one point, its own CEO -- had given up for dead, and newcomers like poll taker Harris Interactive, which experts swore could never adapt to the Web. Their variety suggests just how broad the online opportunity has become."
