Bill Tancer of Hitwise has compiled his company's data to show the number of visits to popular properties at Yahoo!, Google and MSN.
In short, Google unsurprisingly sees the large majority of search visits. Yahoo! Mail gets the large majority of email visits (surprisingly Gmail is far far behind in this measure). Yahoo! News gets 3x the traffic of Google News and Yahoo! Finance gets 3x the traffic of MSN Money Central. MapQuest is still getting the large majority of map traffic with Yahoo! Maps ranked 2nd with less than 50% of MapQuest's traffic.
