No, I've never used it. Or MySpace, Instagram, SnapChat, LinkedIn, FourSquare, etc. I did install Android on my 'phone when it was first released, but at the time its keyboard was hard-coded to specific hardware (the G1 had a physical "jump" button that my 'phone doesn't have, and this was required for typing punctuation). I uninstalled it and went back to Debian, haven't looked back :)
Just to clarify, are you saying you run Debian on your phone? If so how does that all work? What sort of phone do you use?
Yep.
