1. Twitter Is a Tool and Thus Difficult to Censor (...) Twitter aspires to be something different from social-networking sites like Facebook or MySpace: rather than being a vast self-contained world centered on one Web site, Twitter dreams of being a tool that people can use to communicate with each other from a multitude of locations, like e-mail. (...) Unlike Facebook, which operates solely as a Web site that can be, in a sense, impounded, shutting down Twitter.com does little to stop the offending Twittering.
2. Tweets Are Generally Banal, but Watch Out. "(...) tweets by their nature seem trivial, with little that is original or menacing. Even Twitter accounts seen as promoting the protest movement in Iran are largely a series of links to photographs hosted on other sites or brief updates on strategy. Each update may not be important. Collectively, however, the tweets can create a personality or environment that reflects the emotions of the moment and helps drive opinion."
3. Buyer Beware. "Nothing on Twitter has been verified. While users can learn from experience to trust a certain Twitter account, it is still a matter of trust. And just as Twitter has helped get out first-hand reports from Tehran, it has also spread inaccurate information, perhaps even disinformation".
4. Watch Your Back. "Not only is it hard to be sure that what appears on Twitter is accurate, but some Twitterers may even be trying to trick you".
5. Twitter Is Self-Correcting but a Misleading Gauge. "For all the democratic traits of Twitter, not all users are equal. A popular, trusted user matters more and, as shown above, can expose others who are suspected of being fakers. In that way, Twitter is a community, with leaders and cliques. Of course, Twitter is a certain kind of community — technology-loving, generally affluent and Western-tilting."
6. Twitter Can Be a Potent Tool for Media Criticism. "Just as Twitter can rally protesters against governments, its broadcast ability can rally them quickly and efficiently against news outlets. One such spontaneous protest was given the tag #CNNfail, using Internet slang to call out CNN last weekend for failing to have comprehensive coverage of the Iranian protests. This was quickly converted to an e-mail writing campaign. CNN was forced to defend its coverage in print and online."
