This is really over the top.

It's not evangelism, the guy asked "how do I do X?"  I showed him how to 
do it in a few simple steps.

If you take "git" out of the equation it would have been a simple "thank

I could have just as simply replied with the steps needed, however 
s/git/frob/g and it wouldn't have "triggered" any reaction from people.
