Paidcontent reports that Treehugger has been bought by Discovery for about 15 million dollars. Makes sense to complement their green TV programming. I've been a long-time (well as long as its been around) reader of treehugger and was impressed by the way they added new features. When they wanted to do video they posted to YouTube and then vlogged it before moving on to their own player. They also introduced a flavor of digg to cover environmental issues.
