Be careful what you share online

"There’s just way too much information  in internet and a lot of people who are looking for it generally not for good purposes,"

You're getting ready for a vacation or for a night out with friends. As part of your routine, you post an update on Facebook or send a tweet.

Keri McMullen didn't think anything of doing the same thing, updating her Facebook status with her plans to attend a concert. When she got back home, $10,000 worth of her possessions was gone.

"I posted that on my Facebook page, who the band was, where we were going. The band started at 8," she said.

The burglary was caught on security video that the woman had running in her home.

One of the suspects was one of McMullen's 500 Facebook friends, a man she hadn't seen in 20 years.

Police believe her status update tipped off the burglars.

"I will never again put that I'm going anywhere on Facebook," McMullen said. "You really don't know who your friends are."

Stories such as McMullen's inspired the Web sitePleaseRobMe.com, which cautions against over-sharing your information on the Web.

"The more people know about us, especially the people we don't know and can't trust, the more at risk we are," Internet safety expert Parry Aftab said. "Think before you click, think before you post, think before you share too much information."

There are 400 million Facebook users worldwide. The Web site urges caution.

"Pick your friends just as carefully on Facebook as you do in real life … use the privacy tools to restrict more sensitive updates to your closest friends," the company told "Good Morning America" in a statement.

"Use privacy settings, make sure you're using those that lock out people you don't want," she said. "As Facebook said, choose your friends selectively. You're also going to make sure that you don't share information that you don't want to get out there even with your friends.
