SR:siri (Typist's Initials)
Between my carpal tunnel syndrome, working from home, and improvements to Apple's speech recognition, I'm using voice dictation more and more on my emails, blog posts and text messages. Although I know it'll never work in a proper office because it would interfere with my coworkers concentration. As long as I'm working from home I'm gonna continue doing it. Not only does it save my hands for coding, I find it a more natural way to compose my thoughts when writing.
I decided to rock the old "typist's initials" at the end of my correspondence to indicate that my correspondence were being "typed" by Siri a callback to when typists added their initials to l correspondence they typed for their Seniors. This way you know any typos were done by Sir (and missed by me in editing).
