Georgia lawmakers embrace social networking media

According to ajc.com, Savannah Republican, Sen. Eric Johnson now has as Twitter to update the public on Georgian affairs of the state.
Johnson has sent Twitter texts almost daily from the legislative session. On March 12, he tweeted from the Senate floor that his proposal to name tax-dodging lawmakers had come up again, and passed. 'It allows for quick communication with a target audience,' Johnson said in a telephone interview to ajc.com.
What do you think of politicians using social media to connect with their audience? Did Obama pave the way for this sort of communication?
