Which company is the number one player in live search in terms of total traffic and user share?

Live search Hitwise statistics December 2004

The above chart plots total market share Feedster, Technorati, and PubSub over the past month compared to all sites as calculated by Hitwise. Feedster and Technorati jostle for the top position while PubSub is way below. I expected to see a clear winner and was surprised at the results.
