Cool idea although I think you should provide an example newsletter. I'd also like to see some more info on where you'll be gathering this information and how you'll choose to aggregate it.
My server basically spends the week trawling GitHub for trending projects, so the scope of what can appear in a newsletter is kinda limited for now (only stuff that's trending on GitHub). In the future, I'm thinking of looking in other places (Twitter, Pinboard, etc.) for content to put in the newsletter, but the problem there is relating a link in a tweet to a particular programming language — things like PHP and Objective-C are easy enough, but just doing a search for tweets with "#python" and links in them isn't going to return very many meaningful results. So this is just a first release to test the waters and see if there's demand for something like Cccode. If there is, I plan on broadening the scope a bit. For now, though, think of it as "the hottest (GitHub) projects in your favourite language".
Thanks for checking it out!
