When you have a great programmer working on your project he will be cycled to a new project in 2-3 months. Your new senior developer who silently takes over the project is part time because he's working on finishing his education.
No one knows how anything works, except that one guy, who left the company half a year ago. That's how all software development is.
Honestly I think one of the bigger hurdles is the confusion about where to sign up. You have to choose an instance, preferably one that is "compatible" with you. But it hardly matters to the user because it's all federated anyway. Just give me a server that will stay up.
I'm chewing my way through the stormlight archives by Bryan Sanderson. Just finished book 2.5, on book 3 now.
