Microsoft's Kumo Just Another Search Imitator

With by some estimates a 73 percent share of search traffic, Google is driving the industry. Yahoo is still a player, but Microsoft as always been an also-ran and not a very successful one at that.
The revenue generated by search engines is too large for Microsoft to ignore, but what's been leaked about Kumo suggests Microsoft's game of catch-up will already have been leapfrogged by competitors when Kumo goes live, reportedly on June 3.
Simply put: With three large companies in the game, anything one can do is easily copied by the others. Users search habits are hard to change, allowing time for catch-up and making it difficult to convince users to switch or even to start using a second search engine to improve results.
Kumo reportedly improves search results by suggesting more targeted searches capable of bringing users closer to the information they seek. Yahoo and Google have both recently demonstrated similar functionality.
