Twitter Founder INVITED to WH : "[this] must mean they're *really* out of ideas."

Twitter cofounder and CEO Ev Williams is headed to the White House today.

The administration invited him to join a "young business leaders" summit to discuss the economic crises.

As Ev himself puts it -- in a Twitter message, of course -- "[this] must mean they're *really* out of ideas."

A reminder: With 6 million members and 700% plus growth, Twitter makes no money in the US. (It sells some ads in Japan).
