Twitter - a fable for the inexperienced

A Guardian paper blog I came across today demonstrates how web2.0 can go wrong.  The makers of a Conservative webpage aimed at attacking Gordon Brown had their site hacked and also their Twitter overtaken by anti-Tory tweeters because the tweet feed was unmoderated.  I'm still getting to grips with Twitter but it has made me think about how important it is to get sites right if you are an institution or organisation with a reputation to uphold.
