If you’re wondering about the reach of Twitter (clocking in at over 3 million users now) consider the tragedy that’s happening right now in Mumbai. Apparently the police (and perhaps the attackers) are not only aware of Twitter — it’s also part of the problem. The Indian government is asking that the #mumbai hashtag be shut down.
What’s more, with Twitter being an excellent medium for short messages but lacking the space for details, Internet users are now repurposing Wikipedia to maintain a frequently edited page.
