When I was reading one of my favourite blog, ForeverGeek, I came across a link to a PC World article title "30 Things You Never Knew You Could do on the Internet".
It was pretty interesting, especially the part about this nifty little site, Answers.com. Answers.com claims to give answers not links. So, just like you would with Google, you type something into the search engine, say Howard Hughes, and a page of 'answers' are displayed. The information is linked for numerous other websites (such as Wikipedia) and universities.
So from one website, you are given a vast amount of information about your search topic. Having searched Howard Hughes, I now know a lot more than I once did about the man. With a wealth of information and media, and nifty downloads, this site is a must see!
