Ask HN: Programming forums/blogs besides proggit and LtU?

As the title says these are my two main goto forum & aggregation websites about programming. I tried searching HN for others and was unable to locate any other popular ones.

Any suggestions on which ones you find interesting that I should check out? I don't have a particular language requirement, just a forum or blog about any programming which is more than just introductory learn the language type information.
