Vertical Search

It was a cold night in Pennsylvania when Leila Crooks was on Digg.com, the community-based popularity site, and came across a story about a "slanket" - a fleece blanket with sleeves that offers the freedom of arm movement so people can play video games or surf computers while snuggling under a blanket.

Even though Google would prefer not to be a verb, the search giant is just that and more. To Google is to search for products, maps, healthcare plans, cars for sale, images of Britney Spears, coupon sites, new mobile phones, the population of Moscow, blogs on gardening - the world really. And more so now.

As of last May, Google changed the way it serves results pages. It isn't one of the ongoing tweakings to its famed algorithm to help you find what you are really looking for, but a much more significant change.
