I vary. Twitter strikes me as being more like people chatting down the pub than something people might mistake for accurate reporting. Whereas newspapers have a stamp of authority. If I say to you "I hear that SamCam and KateMid are having an affair!" then that's clearly gossip. Put it on the front page of the Guardian and it gathers weight and affects people's perceptions.

Of course there are many websites that fall somewhere in-between, where some people will take that seriously, and assume that "They wouldn't report it unless it was true."
