I once noticed that an AT&T social media VP looked at my LinkedIn profile are commenting on a post that tried to put a positive spin on T as an investment. In essence I wrote that the article was all fine and dandy if you were looking for an income (dividend) investment, but not a growth one.
Do you think company executives would be petty enough to monitor social media and take note of former employees - ahem - cynical views about the company's direction? Not that I give a lick, I already collected my severance and earned compensation so I owe them nothing.
