I was looking through the archives the other day and found that the original article on channel shapes is actually still accurate despite having come out a year ago. It's interesting to step forward in time and watch as things become more and more like what actually was released. I've done similar walks through a longer history of the product, although you have to patiently track through whole concepts appearing and disappearing.
In celebration of this bit of history, I decided to let last year's article stand. I did have a new picture in the channel dev tour drawing style that I wanted to include though.
Update: I'm not sure when the count got off track, but this article turned out to be a day later than one year. Fortunately, now that the product is out, the things that I'm writing about are unlikely to change on a daily basis.
