Well called. Every time I see a story like this (and there have been quite a few of them recently) I always think about how irrelevant the actual specific platform is... The same thing would (and likely did) happen just simply via blogs, wikipedia etc...
I just hope that eventually people stop being so excitable...
Except that it happens a lot quicker than it ever did on Wikipedia or blogs, and reaches a much wider audience now.
Here's the thing people like us tend to forget - the power of Twitter is mobility. Yes, blogs and wikis are powerful publishing platforms for people viewing them on computers.
Twitter is viewable on the most common device in the world, mobile phones. There are very few mobile phones in the world incapable of getting access to Twitter, making it potentially the most widely available social network on the planet.
No computer required.
Add in all that other media democratization stuff, and that's why you get a lot of the hoopla around it you never saw with Wikis and blogs.
I just hope that eventually people stop being so excitable...
