More than ever, Web 2.0 technologies offer governments a way to improve citizen services and communication. The problem for government information-technology officials is deciding what tools to implement and how best to implement them. A solution is MuniGov2.0, a coalition of mostly city and county IT professionals who collaborate and share best Web 2.0 practices. Founded by Bill Greeves, the IT director of Roanoke County, Va., the group meets weekly in Second Life, a popular online community, to discuss topics that include Second Life, Twitter, technology incubation and other Web 2.0 technologies. Greeves formed the group when he failed to find any resources on Web 2.0 best practices by local governments. MuniGov2.0, which is barely three months old, already has about 175 members, and a Second Life office that consists of virtual conference rooms, demonstration halls and other meeting spaces members can use to collaborate. With budgets tightening, it's clear that Web 2.0 technologies could save governments money. For example, Missouri recently hired its first Second Life recruit -- a seemingly innovative and cost-effective strategy for human resource departments.
