How come we first get the almighty git software for free, then the next thing happening is people flocking to "hosted" services that provide very little on top of git for the vast majority of projects (apart from the social networking effect of course, but that also means your project has tens or hundreds of issues and build status "failing"). Then people bitch about gh on HN in a consumerish "coke-vs-pepsi" manner. Have F/OSS devs no self-respect? If you're into F/OSS, why do you lead your peers into a github silo where clicks to the content you create with lots and lots of effort in your spare time only helps big data, and which is even blocking indie search engines?
