You know the world has gone to hell in a handbasket when you learn that in the last 12 months our netizens sent 25 billion tweets (short messages of up to 140 characters).

As if that nonsense were not bad enough, Twitter, the four-year-old startup that lets the little (mostly) twits send all those tweets, today disclosed it’d raised another $200 million at a $3.7 billion valuation.

Silicon Valley VC outfit Kleiner Perkins Caufield Byers led the latest round with $150 million.

By the way, does Twitter have a business model, one that’s been proven to work?

Is Twitter even profitable?

For what it’s worth, we too have a Twitter account here.
