Twitter's poor earnings in focus at meet

SUN VALLEY, Idaho: It turns out the media elite aren't so different from a lot of less affluent people: They think Twitter is a great communications tool, but can't figure out how the online messaging service is going to make money.

The recurring doubts about Twitter's moneymaking potential cropped up again on Wednesday (local time) as an exclusive media summit hosted by investment banker Allen & Co got under way at the posh Sun Valley resort.

One of the first sessions focused on how to capitalize on digital media. Twitter quickly became a focal point of the discussion because it has emerged as one of the Internet's fastest growing services this year.
