90% of the time I see grammar nazis doing their thing, it's never about protecting the "sanctity" of grammar - it's more about exerting control and attempting to enjoy the feeling of being right.

The other 10% of the time are from people that know its purpose is to be a vehicle for the communication of ideas, and will also make up statistics.

I love me some irony, and felt this comment train was more engaging than the post itself; so I'm contributing to its further development.
