Web Utilities:
 
Firefox.  Better security.  Standards compiant.  Open Source.  Lots of great extensions.
Tab Mix Plus  Firefox Extension to better manage tabs in Firefox.  Must Have.
Stumbleupon  Firefox extension for browsing "random" webpages based on your preferences.  Must Have
ScrapBook  Firefox Extension to handle saved pages.  Can also be used for "websucking".
Web Developer  Firefox extension with lots of options.  I don't use this one all that often.
Firebug  Firefox extension for debugging your javascripts, etc.

 Opera is a secure, lightweight, standards compliant browser.  Not open source, no extensions, but still superior to IE.

 Internet Explorer is another facet of Microsoft's lame attempt at world domination through insecure software.

  NVU is a free open source WYSIWYG html editor.  It's not the best when you migrate to CSS, but you can't beat the price.

Google Earth.  Know where to send the cruise missiles.

Pages I used to visit regularly:
Google.  Go figure.
Lifehacker.  Don't live to geek; geek to live.
Geekologie.  Offbeat news for geeks.
Wikipedia.  A world of useless facts.  Ever wonder what happened during the second Anglo-Dutch war?
GoogleNews.  Better than CNN.

Other stuff:
The Meaning of Life.  Ever wonder what it's all about?  Read On.
