US-INTERNET-TWITTER

Twitter hit Wall Street with a bang on Thursday, as an investor frenzy quickly sent shares surging after the public share offering for the fast-growing social network. In the first exchanges, Twitter vaulted 80.7 percent to $47, a day after the initial public offering (IPO) at $26 per share. While some analysts cautioned about the fast-changing nature of social media, the debut led to a stampede for Twitter shares.
