Diffen

I found Diffen a few days ago while searching for the differences between a Psychopath vs. Sociopath (and I'm happy to announce that, while I have a few of the traits of both, I'm fairly certain I can't be classified as either.).

From the site:

What is Diffen?

Diffen lets you compare anything.

What is the difference between DVD+R and DVD-R? What is the difference between a pub and a bar? An alligator and a crocodile? What is the difference between 401(k) and IRA? Treasuries and bonds? AMD Turion and Athlon processors? How is a Pentium Core 2 Duo different from Pentium Dual Core? How does the work environment at IBM compare with working at Microsoft? How does living in Seattle compare with living in Amsterdam? What is the difference between a Plasma TV and an LCD TV? Cal Tech and UCLA? Yankees and the Red Sox?

You can find or write all these comparisons on Diffen.
