Twitter.com and it's Viral Widget Success... Why?

Having looked closely at Twitter.com the always on solution to keeping in touch with friends.

I couldn't see how the attention it receives is justified by the value it offers the user.

There are almost half a million pages of cached content in Google's index, Twitter's home page Pagerank is 8 and it's for thousands of delicious link and viral exponential alexa growth, something seems to be working.

Although I'm not 100% sure about this, I've decided to add the twitter viral widget to my blog.
