This meta search engines name certainly lets your imagination run wild, but atleast they remember special days like today. En Memorium:
Thats a nice thing that a search engine remembers this day, but im not sure if Google don't even do this
Well I found this on their website so i'll just cut and paste so their "message" comes out right: "The inspiration for Dogpile came when its founders noticed that different search engines often return different results for the very same term. The more engines they searched the more results they found. Following this discovery, the founders set out to create a way to bring the Web's best search engines together in one place to deliver more comprehensive and relevant results. To capture this idea, the founders borrowed a sports term used to describe players piling on top of one another in the celebration and the Dogpile search engine was born! "
"Dogpile" is an idiom meaning a bunch of things thrown into a pile (usually a bunch of people on top of one person -- in other words, gangning up on him). I guess the idea is that it's taking a bunch of results from different sources and throwing it at the user.
