It's work. One of the first things I wrote about Twitter. Scheduling - selectively reading then sharing a few things of interest, then spacing them out over a day - that's different. All this noise, all these automated feed driven tweets, is just that, noise; and then some of the vary same people feeding the machine are the ones decrying the platform's usefulness. See also FB; one thing G+ has going for it is that the API hasn't opened up to this kind of automated, robo posting.

I still really like Twitter; what it is for me isn't what it is for everyone else, I get that. Still.. as a biz communicator I look at so many brands and how they run their Twitter (all SM really) and think, 'damn they are doing it wrong.' 

And FWIW, one day soon I'm gonna go on a "humble-bragging" rant, so world... consider yourself on notice. ;-)
