Matt Linderman of 37signals - A reminder about the power of email:

"It was a reminder of how much power there is in email. We forget that the RSS-centric world we live in isn’t the one many (and probably most) of our customers live in. They don’t have the time or energy to keep up with the constant stream of info at our blogs. That’s why the old-fashioned occasional email update — which gives people the juiciest bits and leaves out the rest — still has so much power."
