>Or of course you can merge the commit from the web. Seriously, you can merge it, without even getting it on your machine (to, you know, test it, read it, etc.), from your web browser. That’s stupid, right?

I don't agree with this. It's actually quite useful. Each time a pull request is opened Travis CI runs the tests and shows green or red for passed/failed tests. So you don't even have to fetch from remote and run tests locally.
