It's a simple message and good advice.
First Twitter is not a “site” but a message system.
And yes there are kiddies chatting on it. Yes there are youth in Iran risking their lives to send information out of a country that is total media blackout.
Until this event I would have had NO interest in Twitter at all.
I have made a number of “friends” over there and truly am concerned for their safety.
If that makes me a “fool” then so be it. And since I am approaching 62 I guess that would qualify me for being an “old fool”.
