It’s not just about efficiency, it’s about responsibility. I love decentralization when I can avoid dealing with BigCo, I hate it when I’m responsible for fighting spam, ensuring my services stay up, not getting hacked, and so on. All of these tasks are a requirement as soon as collaboration is in the picture.

You've got a point there. I'm just so sick of all this. The Internet's a great thing, but it just seems to be going downhill with corporate interests.

I disagree. The popularity of GitHub amongst the programming community means that ease of use / convenience is more important than the notion of “decentralization”. Otherwise, people would already be setting up their servers for hosting git repos.

That's really what I meant by efficiency. Ease of use increases that for businesses, that's the only reason they really care about ease of use of products they want to buy.
