You design the weekly newsletter
Every morning at 6 AM your editor assembles a slightly idiosyncratic and biased newsletter from the previous day's posts on TreeHugger. Every Friday he crunches the numbers on the readers' choices of the most popular posts from the daily and puts them all together in one convenient place, the Weekly newsletter. You pick'em and we print'em. As a sample, here is the weekly that just went out.
So sign up for the daily or weekly newsletter. Try it, you'll like it.
