Without further ado, here’s the list of five reasons why Google should fear (or more likely, buy) Twitter:

It’s Personalized: If Google is a vast library with only one librarian to guide you around (who can be hard of hearing depending on how complicated the information is that you are looking for), then Twitter is the same library but with all of your friends (and other individuals who you trust) standing around different areas of the library to point out the information that you should actually care about.

I am definitely adding this to my “explaining Twitter” repertoire.
