Share a blog or website that you’ve found meaningful and rewarding to visit (if it's Pinterest please share why this has become such a raging fad).
I don't know if it's meaningful, but there is one blog that makes me laugh every single time I visit.

This thing is really funny, and probably the most normal-sounding mom stories on the Internet.
As for Pinterest, I really like looking at the pins of my friends. Then I pin things, but never go back to look at them. Maybe someday I will use it more/better.
