Occasionally, I forgo my morning commute and "work from home".
Of course I can't actually work at my home because there are too many short people (a.k.a. my kids) climbing my leg and poking at my keyboard while I am trying to have serious discourse on the phone. I solve this problem by working at the local public library about half mile down the road.
Over the past couple of years, I have had about a dozen "library days" and somewhere in that relatively brief time span, an interesting phenomenon has taken hold.
This library has a bank of about 15 PC's along one wall. When I first started spending "a whole day at a time" there, I noted sporadic use of the PC's. Usually, at least half the stations were open at any given time. Mostly, it was 20ish men reading profiles of women on dating sites (yes, I am one of those annoying over the shoulder readers).
Over the past six months, this has changed. Now, the PC's are essentially at full capacity with waiting lists of local patrons anticipating their turn at the keyboard. The new patrons are mostly middle-aged, a mix of men and women, and every damn one of them is logging onto Facebook.
I don't know if this is good or bad but it is clearly an epic phenomenon.
