I know professors hate you. You're open to editing by the general public, which means your information may or may not be accurate. That being said: I love you. I love how easy it is to find stuff on whatever I'm curious about at the moment, be it the run of Doug on Nickelodeon, or the strengths and weaknesses of PHP. I love how simple you make it to find other sources for projects, because professors don't like to see "Wikipedia" on a bibliography.
And I love how reality has become a commodity. :-)
