The daily comic "Userfriendly" is the first point where every surf session should start. There you get information about the employee working for an ISP and their wisdom about Linux and WINDOWS. Every day actual themes coming from the Linux community are spiced with humor. If you have always wanted to know what Microsoft's Anti-Linux-Group looks like and how new NT administrators are educated in the Camp of Redmond, you should regularly look at this site.
The actual daily "static" is at http://www.userfriendly.org/static/
the "Imagery Intelligence Gallery" (IMINT), you
will find a big collection of satellite and arial pictures from
the last 50 years.
Many web sites
