NEW YORK (

TheStreet

) -- "Chinese Facebook" is a popular search topic after

Renren

(RENN) - Get Report

, which is often referred to as the Facebook of China, launched an initial public offering on Wednesday.

Renren shares surged in their first day of trading, after the company priced its IPO at $15.50 per share.

Shares climbed to a high of $24, but were dropping about 8.5% to $16.50 in recent trades Thursday on volume of nearly 27 million shares.

After the original Facebook was banned in China, Renren emerged as similar service. Renren is primarily used by students and has 117 million activated users.

Its closest competitor is Kaixin, which appeals more to adults. Kaixin is expected to go public next year.

"Wiggly worm" is a hot net search after close viewers of royal wedding photographs spotted a toy worm in the hands of a 3-year-old bridesmaid.

Eliza Lopes, granddaughter to Camilla, Duchess of Cornwall, can be seen holding a small fuzzy pink toy that Prince Harry gave her during the carriage ride from Westminster Abbey to Buckingham Palace after the service, in order to help distract her from the overwhelming crowds.

Camilla, the wife of British Prince Charles, said her granddaughter loved the toy so much that she refused to let go of it while the official wedding photos were taken.

"Black Hawk" is a trending search topic after aviation analysts said the aircraft blown up by the team of Navy SEALs who killed Osama Bin Laden was a stealth Black Hawk helicopter.

The elite military team was forced to destroy the damaged helicopter before it left the Bin Laden compound in Pakistan on Sunday night to make sure no one would be able to collect, examine or reconstruct the secret chopper.

According to a report from

ABC News

, most of the remaining pieces of the U.S. helicopter were recovered by Pakistani officials on Wednesday.

"There are probably people in the Pentagon tonight who are very concerned that pieces of the helicopter may be, even now, on their way to China, because we know that China is trying to make stealth aircraft,"

ABC News

consultant Richard Clarke said Wednesday evening.

"Bin Laden DNA" is a popular search topic after President Barack Obama and his administration said they used "multiple methods," including DNA testing, to confirm that American special forces had in fact killed Bin Laden.

The government had been considering releasing an image of Bin Laden's dead body to further confirm his death, following reports of skepticism from around the world. However, U.S. officials ultimately decided to hold onto the photos to avoid igniting anti-American sentiment.

White House press secretary Jay Carney said that in an interview with

CBS'

"60 Minutes" on Wednesday afternoon, Obama told interviewer Steve Kroft that there is "no doubt we killed Osama Bin Laden."

"You will not see Bin Laden walking on this earth again," Obama said in the interview.

More information about the DNA testing and the facial recognition methods through which officials confirmed Bin Laden's death will likely become available in the future, Carney said, but visual evidence, such as photos or video footage from the raid, won't be released.

The chatter on Main Street (a.k.a. Google and other search sites) is always of interest to investors on Wall Street. Thus, each day, TheStreet compiles the stories that are trending on Google, and highlights the news that could make stocks move.
