Popular or not, twitter and such totally public-directed info sites shouldn't be expected to
be any more believable than than any other rumor mill.
There can be good information, and there can be utter misinformation.
CB radio was much like this in the late 70s.
To hear that NBC is using Twitter is kinda like hearing that the President of Chase Manhattan Bank
wears those athlectic shoes that light up and have wheels in heel.
Serves 'em right...
Tasteless messages? It's like the CB, where the worst in human nature is displayed.
Why would major networks want to lower themselves? I know..... popularity, but
it's too much like wishing to be something you're not.
It would be a great time for a competitor to use the opportunity to discredit Twitter AND NBC.
