No IPO soon: Twitter raises another $200M

SAN FRANCISCO (AP) — Don't expect Twitter to be tweeting about an initial public offering any time soon.

The popular online communications service has raised another $200 million so it can keep growing without Wall Street's help.

Kleiner Perkins Caufield & Byers, one of Silicon Valley's best-known venture capital firms, is leading the investment announced Wednesday. Twitter also added two successful entrepreneurs, Mike McCue and David Rosenblatt, to its board of directors.

The funding was first reported by the technology blog, All Things Digital.

Twitter's association with Kleiner Perkins is likely to add to the intrigue about the moneymaking potential of a service that each day blasts out more than 65 million short messages, or "tweets," limited to 140 characters.

Kleiner Perkins' past Internet bets include investments in online search leader Google Inc., now worth about $190 billion, and leading Web merchant Amazon.com Inc., now worth about $80 billion.
