Please contribute to the Sitecore content audit! I want a master list of your favourite resources – including any overlooked documentation on the SDN. Anything goes – blog articles, twitter feeds, code samples, downloadable presentations, et al. 🙂 Blogs from sitecore.net as well!
Make a pull request or contact me on Twitter (@mhwelander) or via e-mail (maw@sitecore.net) to add content: http://sitecore-community.github.io/docs/
