I Am not feeling forced to use it. I use it because it is easier for me as an individual developer. I use readthedocs because they have better uptime than my own servers.n All the reasons i use GitHub are good choices for me.

I get the economics of centralised vs decentralised service provision - it's just ironic that GitHub is facing load balancing problems precisely because they have taken a distributed technology and made it, de facto, a centralised technology.

We can imagine a perfect storm of GitHub going down just as someone pulls a vital package from npm and Google losing jquery CDN; all Of a sudden the web will stop working.

It's amazing how fragile we can make a system designed to be resilient - I presume there is a real cost with keeping things distributed that a good economist could explain to me
