For me, Twitter is an essential tool to keep up on all the various initiatives, whether it’s challenges, open gov, efficiency competitions, new initiatives, or innovation. I “follow” Fast Company, my Congressional representatives, the White House, GovExec, FedNewsRadio, CNN, and about 80 other “sources” of information (including GovLoop). It’s the only way to keep in touch and keep informed in our information-rich society. I’m a big “follower” of new initiatives and a news junkie. Twitter is not just for following celebrities. It is a powerful aggragator of information. You can even follow Rep. Issa if he floats your boat.
