"The best tools aren’t always that cool. Groupon chose e-mail because it’s simple and universal." We see facebook / twitter / rss integration on nearly every website in the universe, but seems that good old fashioned email list building often takes a back seat. In my experience nothing drives consumer actions like email - FB is casual, twitter gets clogged for people using it, etc - if you're going to get somebody to click somehing feature email!
