Apparently, Michael Bloomberg likes to slum it up with the rest of us cubicoids.
From the Governing.com blog:
For all the innovations that are spinning out of NYC under Mayor Mike Bloomberg, the idea that almost no other mayors are stealing is the easiest one to implement. That's the open-air office, the egalitarian "bullpen" that Bloomberg, whose spare cubicle is no fancier than any of his underlings', brought to City Hall from his media company.
If you want to be like Mike, nothing could be simpler than doing the bullpen thing. We're talking plaster work, not politics.
Talk about ending closed-door government!
