As someone who finds organization a challenge, I am beginning to more deeply appreciate things like paper clips, rubber bands and...Tweetdeck.
On Sat March 19, I attended the COMMUNITY BLOG expo hosted by The Daily Local and the Daily Times: two wonderfully active papers in "Crowd sourcing" and social networking. Crowd sourcing: say you're somewhere a reporter is not and you want to share something that the public-at-large should see: you can upload a video or pic to responsive papers who will then make it "airborne" public information! Instant to-the-minute news. Social Media expert/speaker Bob Garrett mentioned that, because of Social Media, he heard of Japan's plight within 8 minutes of the first happening of recent disasters there.
Another story of Bob's was of one "SM pro" who has 2500 active profiles .....I'm dizzy. Of course, you need to watch out for the self-appointed-paparazzi-type- iphone-welding-starved-to-be-famous...hey wait..that's ME!.....Anyways, the good news is ADD-types like my self can find some pretty spiffy ways to manage their "social presence" more efficiently such as Tweetdeck, Hootsuite and Ping.
If reaching lots of humans planet-wide (without spending lots-o-bucks) is your goal... you live in the right times.
