I was going to make a post about the Xbox 360 store shutting down and say "countdown to the community-run alternative"
But it turned out my friend Derf (maker of Console mods .wiki) had been working on a homebrew replacement in anticipation of the shut down and within 24 hours of the Xbox Live Store on 360 shutting down his homebrew store went live!
How amazing is that? The modding community *rules!*
