Now that’s what we call efficiency.

Not six hours after being officially sworn-in as the District’s fifth elected mayor since Home Rule, Adrian Fenty’s presence is already being felt on the city’s official homepage. Gone is the image of former Mayor Anthony Williams atop the page, as is his “Mayor’s Welcome.” Both have been replaced by Fenty. Williams’ blog is also gone, though it won’t soon be missed — it’s last entry was dated March 23, 2006. And in case you were wondering if Fenty was going to take it slow today, think again — his official newsroom is abuzz with activity, with eight press releases announcing a number of key appointments.

Welcome, Mayor Fenty.
