A piece of software called Alexa (http://www.alexa.com) gives the Internet
a friendly face. Once installed, it puts a tool bar on your browser that lets
you find out more about the sites you visit. Buttons reveal who 鈥渙wns鈥� the site
and how popular Alexa thinks it is. Alexa also suggests other sites you might
want to look at. The software is part of the Internet Archive project
(http://www.archive.org) and if you can鈥檛 contact a site and a version of that
page is in the archive, Alexa will dig it out for you.
