Ironically, a couple of days later, on 8th February 2011, the UK's Press Complaints Commission ruled that Twitter messages were not private, and therefore quoting them was not an invasion of someone's privacy. To read the ruling and background behind the case, click here.
They decided that although someone's tweets were distributed to only the people who were following them, any of those followers could distribute the tweet to any of their own followers, and therefore the 'tweeter' had no control over who could and could not view the text.
From a writer's perspective, it's useful to have a clarification like this, because any quote can add authority and credence to an article you may be writing.
However, I would still urge a word of caution when quoting a tweet. If you do want to quote a tweet, then you should (as with ANY quote) attribute it to its source. For Twitter, this means attributing the tweet to the name of the twitter account, (which begins with the @symbol) and not the Tweeter's Profile name. Search for one of Twitter's most famous and prolific tweeters, Stephen Fry, and you'll see around 20 profiles. Now some are clearly not Stephen Fry, but others aren't as clear cut. In other words, a Twitter account may not actually represent who they claim to represent. (Twitter strongly encourages 'spoof' or 'fake' accounts to make it clear that they are not the real thing, but that doesn't guarantee anything!) Therefore, by attributing the quote to the Twitter account, rather than the name of the person the account purportedly represents, should prevent you from getting into any trouble!
As an aside, if anyone reading this post isn't on Twitter, then I would encourage you to consider it. There is a huge number of writers on Twitter, sharing a lot of ideas and offering support. It doesn't matter whether you write non-fiction, or fiction, you'll find many like-minded people and well-known writers there.
