Twitterer to be sued

I am sure that there will be much debate about the ownership of comments on twitter but maybe this case reported by the BBC from Chicago may have some bearing on future policy.

A tenant who used the micro-blogging service Twitter to complain about mould in her Chicago apartment is being sued.

According to the report

Horizon Group Management filed a lawsuit that has accused Amanda Bonnen of defaming the company with her tweet.
She sent out a message that said "Who said sleeping in a mouldy apartment was bad for you? Horizon realty thinks it's okay."
