I've started including blogs from individual software engineers. If you know anyone with interesting content, feel free to make a pull request. :)
Done. I guess next step would be categorizing them since, for instance, now I'm thinking of all the security-related blogs...
But then you have multiple dimensions: corporate vs. individual and security vs. non, so you have to start using a real CMS or your own code and tagging, not a plain file list on github.
