(Newser) – LinkedIn had its IPO today, and there was an investor feeding frenzy before the bell had even rung. The shares wound up opening at $83, an 84% premium on their $45 offering price, the Wall Street Journal reports. They're currently trading at around $105—having peaked this morning at $122. It’s the biggest Internet IPO since Google, and has raised fears that investors are buying into a new tech bubble.

LinkedIn is also the first social networking site to go public, and is seen as a good indicator of how a Facebook offering would go over. “In Silicon Valley, everyone wants this to be a success,” says one tech adviser. “If it works, there's going to be a big push from a lot of social media companies to try to get out before Facebook does. Because once Facebook comes out, they're not going to be able to get any analyst attention.”
