Some people should not be allowed to have Twitter accounts. And by "some people" I mean one of my Senators, Chuck Grassley. The Senator is apparently fed up with Obama taking trips abroad and tweets:

Pres Obama you got nerve while u sightseeing in Paris to tell us 'time to deliver' on health care. We still on skedul/even workinWKEND.

Pres Obama while u sightseeing in Paris u said 'time to delivr on healthcare' When you are a 'hammer' u think evrything is NAIL I'm no NAIL.

No matter what you have to say, when your manner of saying it makes you sound more like a sulky middle schooler than a long-serving US Senator, it's time for someone to take the Blackberry away.
