Perhaps You’ll Stumble Upon the Best Search Results for You at StumbleUpon.com
The Internet is an incredibly huge place, and it is difficult to find your way around. It is hard to imagine a topic that there is no information on in the Internet, which makes it an incredible tool for research and learning. The problem is how do you find the information that you want?
The two basic ways of finding information on the Web are with Web Directories and Search Engines. Web Directories are lists of pages or sites that have been collected by a real human being. The information in a web directory is very useful, if your interests and the information you need are the same as the interests of whoever put the directory together. The other disadvantage of a web directory has to do with the ever-expanding nature of the Internet: there are new sites and new information on a daily, almost hourly basis. It can be very easy for a web directory to fall behind and become irrelevant.
Search engines depend on two things. First are Web-Crawlers, or Spiders. These are computer programs that survey as many pages as it can on a constant basis. The results of these searches are collected and indexed by the search engine. When a search inquiry is made, the search engine will deliver the results in accordance with an algorithm which ranks the results of the Spider's search. The problem is that these results are based on mathematical or mechanical formulations, and may or may not be of use to a breathing human being.
StumbleUpon.com uses the best of both systems. StumbleUpon uses the features of an algorithmic search engine but the results are filtered using Social Networking Strategies. Social Networks work in favor of StumbleUpon, with feed from Facebook and other social sites. The use of Collaborative Filtering and Machine Learning help to insure that StumbleUpon will find the search results that are most useful for you.
