Looks like our Governor (Gov. Jay Nixon, or likely someone from his staff) started to make some regular posts to his Twitter account on the 2nd.
I found it a little bit interesting that the profile picture is of the nation's Capitol and not Missouri's.
May as well point out a couple of other Twitter accounts in Missouri State Gov't, while I'm at it.
Transform Missouri (I have mentioned this one before)
Missouri Department of Conservation
Public Involvement Coordinator for the Missouri Department of Conservation
Missouri's Department of Revenue's Web Team has been testing one to post about website updates
Of course, there are other's out there as well. Feel free to post your favorite Missouri State Government twitter or simply another Missouri State Government Twitter that you follow.
On another note, want to know more about Missouri's CIO, you can check out Government Technology's article, Meet Bill Bryan, Missouri's New CIO.
