I use all of these, and I believe most of us do to. Maybe the alias is not the same, but I'm sure we can reach some kind of agreement. 

There are many benefits in this, such as getting nice alias that we did know about, or uniformization of the alias we use as team, which will make it easier to use the computer of each other (which is good for pairing).

Maybe you do use `co` for committing, but it is widely used to `checkout`, so you might as well change your ways (and this goes for all of us, regarding any configuration).
