It looks like GitHub removed the old rankings completely. For example, I can no longer see C projects ranked by star count. https://github.com/languages/C/most_watched redirects to https://github.com/trending :( To be honest, I mostly used those pages to satisfy my own vanity. My C project (https://github.com/ggreer/the_silver_searcher) just beat Arduino (https://github.com/arduino/Arduino) and was gunning for mruby (https://github.com/mruby/mruby).

No not silent majority, not even close. Naming a single instance is not representative of the real-world at all. Unfortunately Amazon/Azure are coy with their numbers but I expect there is likely an order of magnitude more instances deployed on Amazon than Azure. Some rough numbers to provide some meaningful context of Microsoft's overall server market share: Microsoft only has 11.62% of the total web server market share of active sites, 12.86% activity from the top 100M busiest sites: http://news.netcraft.com/archives/2013/03/01/march-2013-web-... Only a fraction of the top internet sites are deployed on a Microsoft platform: http://www.seomoz.org/top500 C# (the most popular .NET language) is the 12th most popular language on GitHub: https://github.com/languages/C%23

You could look at e.g. https://github.com/languages/C and http://sourceforge.net/directory/language:c/freshness:recent.... Interesting projects could include Linux/PostgreSQL (current) and Redis (pretty new); I tend to steer clear of unmaintained software, so I cannot help you there.

ServiceStack is used to handle all of StackOverflow Careers 2.0 BackOffice Web + MQ services, making use of all its components e.g: Redis Client, OrmLite, ServiceStack's JSON, etc). I've personally led dev teams that have put ServiceStack in production enhancing existing internal CRM / SharePoint systems (where WCF wasn't able to run) for Man Investments and EON. I personally know many other IT consultants (professionally) that continue to deploy instances of it for their clients. We've collected a number of testimonials that we'll publish after we re-design our website. There have been over 100,000 total downloads in this past year alone, and I've had a number of chance run-ins with dev teams using it (even in my home town!), which I write a bit about it here: http://www.servicestack.net/100k-downloads/#feedback The above page also provi

We're working on Mercurial support too. There are loads of .NET and C# projects on github though: https://github.com/languages/C%23
