@stortebeker: Oh dear! What happened here? Here is a high quality post (complete with video!) on a visually appealing topic, not just for sustainability nerds, the whole thing posted by none other than eco alex on the ecoTrain... and the result? 40 upvotes with zero comments in three days!!! Scary to say the least. At the same time I realize it's been almost a month since I've published a post, and the parallels scare me even more.
