Excerpt from a Twitter reality check
Still, the company's leaders face weighty challenges: how to better make money from the service's voluminous and fast-growing user traffic; how to banish for good the notorious "fail whale" icon that appears when the site is overloaded; and how to help users better navigate some 200 million daily "tweets."
Bill Reichert, a venture capitalist at Garage Technology Ventures, is among those who doubt they can pull it off.
"It's hard to find any other company that has been so successful by some measures be so incredibly lacking in innovation for so long," he said. "Twitter is no longer cool or exciting. It's just there, like texting. Only I pay for texting."
