Should you care if the government can see your Tweets?

Today's paper has an interesting story about a UK man being arrested and interrogated by police about a joke he posted on his Twitter account.

Although it involves the UK -- not the US -- government, this story is a good illustration of what we were talking about during last week's class regarding new (digital) forums for social interaction, and related expectations of privacy. It speaks to David's question about why exactly we might be concerned with the government being allowed to look at our Facebook pages, etc.

I think this anecdote points up an important problem with the new digital environment, in that it's often difficult to understand context. It raises questions about how we should treat (protect?) social networking spaces.

Related (though not precisely the same issue), are instances of police actions taken against activists in the US using Twitter to exercise their rights to speech and assembly.
