Perhaps you've seen the popular internet method of gauging the kinds of questions people are asking their internet search engines by beginning to ask a question (by typing it into the search window) and seeing what the search engine suggests. The product is usually some humorous and/or surprising quirk of popular culture. Apparently, asking the three most popular search engines, "Why is Glenn Beck," produces a similar result.

Bing
Users of Microsoft's relatively new search engine, Bing, seem to be mostly concerned with either why Glenn Beck left CNN or why he's on TV at all...

Yahoo
You'd think since Yahoo search is now powered by Bing that the two would produce identical suggested search results, however there are some variations. Some of the questions are duplicates, others are loosely translated (eg. "why is glenn beck still on the air?" at Bing is translated to "why is glenn beck on tv?" at Yahoo). Yahoo users also had a soft spot for Mr. Beck's health.

Google
With a 72% share of all internet searches in the U.S., Google is by far the largest search engine in the country. And based on the output of my little experimental query, either the search results have been gamed, Bing and Yahoo apply some Beck-protecting filter, or, Google users are less concerned about why Beck left CNN as they are other things.

Just sayin'.
