OMG I just read this fantastic note from Edson in reply to Kris a decade ago:
Edson wrote:"I find things like facebook and tweeter very distracting and disruptive to my concentration on my daily activities. in principle, I am against the amount of personal exposition people got used to recently and, besides, do not consider myself interesting enough to keep people informed about what I do or think.
Speaking from my heart, I couldn't agree more!
And so, thought I have to mention it.
As I too would never use fakebook or anything else from their, or doogle's, portofolio of exploiting human data, privacy, and weakness.
(Sorry, not criticizing anyone, just contributing my personal FEELING

)
@Kris: A (late) ton of thanks! Will look at it, only just found it.
