Elliot Cohen, whose Summer of Code project I am mentoring, has started a project blog at http://elliotpbnt.blogspot.com/
I also noticed that http://planet.python.org/ has started aggregating a bunch of SoC project blogs (including Elliot's)
The original post was in the categories: python software_craftsmanship summer_of_code but I'm still in the process of migrating categories over.
