It's back. Megabus , which offered low-cost bus service to Las Vegas from L.A. in 2007 and then withdrew from the market, will begin service between the two cities on Dec. 12, it announced Wednesday. Like Greyhound , which also has recently introduced low-cost service to Las Vegas from L.A., Megabus hopes to lure Vegas-bound Angelenos out of their cars and onto modern coaches with one-way fares starting at just $1. “We've seen impressive growth throughout North America and are confident that our 21st century double-decker buses with Wi-Fi and power outlets combined with our outstanding prices will be a success among California and Nevada residents,” said Mike Alvich, Megabus.com's vice president of marketing and public relations.

Jada Pinkett Smith, wife of Will Smith, is addressing those open-marriage rumors again - less than two weeks after chatting about it on HuffPost Live. Now, the Ministry heard a "no" the first time around when Pinkett Smith was asked flat-out, "Is it true?" but we appear to have been in the minority. So much so that Jada took to Facebook over the weekend to try to explain herself, framing her comments as a discussion of trust and love. Or, as she put it, TRUST and LOVE. Can you hear her now?

A study on how people use social networking websites such as Facebook confirms what many of us suspected. Women who post loads of photos of themselves on their sites are conveying some strong personal characteristics, according to new research. These women are more likely to base their self-worth on appearance and use social networking to compete for attention. The study involved 311 men and women with an average age of 23. In order to better understand aspects of social networking behavior, the researchers looked at the amount of time subjects spent managing profiles, the number of photos they shared, the size of their online networks and how promiscuous they were in terms of “friending” behavior.

When your TV is longer diagonally than most people are tall, that's when you have the largest LED TV on the planet. That's what Sharp has. The Japanese company Tuesday introduced what it contends is the largest LED TV in the world, announcing and launching the 90-inch Aquos LED TV. The TV is 4 feet tall, 8 feet diagonally and more than 6 feet wide with a depth of 5 inches. Sharp says it  weighs 141 pounds.  In addition to its impressive screen size, its other features seem solid.

It was kind of creepy, but it also had potential to be useful. But in the end it didn't matter because Facebook has pulled Find Friends Nearby as unceremoniously as it debuted it. After the feature was introduced to the world Sunday by one of the Facebook engineers who created it, Facebook pulled the feature not long after, taking it offline the very next day. Find Friends Nearby was definitely not a polished final product, but the feature...

A survey released this week found that there were more teens and young adults who said they use Tumblr on a regular basis than those who said they use Facebook. Fifty-nine percent of respondents between the ages of 13 and 25 said they use Tumblr regularly; 54% said they use Facebook on a regular basis. Among those 13 to 18, the percentage who said they use Tumblr regularly was even higher -- 61% compared with 55% who said they use Facebook regularly. The survey was conducted by Y Combinator start-up Survata.

SAN FRANCISCO — How does a 28-year-old make $400 million in 18 months? With the right idea at the right time in mobile apps for smartphones. Kevin Systrom won the start-up sweepstakes this week when Facebook Inc. said it would pay $1 billion in cash and stock for his photo-sharing app maker, which has a loyal following of 30 million users but never made a dime. Facebook Chief Executive Mark Zuckerberg called Systrom to personally negotiate the deal for the social media giant, which is expected to fetch a valuation of $100 billion as soon as next month when it begins selling shares to the public.

Facebook is hoping to pique the interest of young people with a new iPhone messaging app that lets them “poke” their friends. The giant social network on Friday rolled out Poke, which sends texts, photos and videos to friends that self-destruct within 10 seconds. The messaging app is a direct competitor to Snapchat, which has skyrocketed in popularity among teens who want to send private messages that pop up and, once read, disappear. (Old timers on Facebook will remember that old-school poking - as in saying hello -- was once all the rage among the desktop crowd.)

Maintaining privacy in the digital age is no easy feat ? particularly if you are the subject of a movie. And yet Angela Wesselman-Pierce, the woman who holds the key to the mystery at the center of "Catfish," has remained a quiet enigma for more than eight months since the movie became a sensation at the Sundance Film Festival. She's avoided requests for interviews about the film, which is being marketed as a documentary thriller and has taken in more than $1.6 million at the box office since its Sept.

A month after two of its two most important moments -- its jump to Android and its acquisition by Facebook -- Instagram has already reaped some of the rewards, seeing its number of unique visitors grow by 78%. The dramatic gain in traffic placed the little photo filtering mobile app at the top of the web for growth in April, according to ComScore Inc., which released the statistics Thursday.  Instagram brought in nearly 14.6 million...
