U.S. embassies used to pass important security alerts to Americans abroad through word of mouth, Janice Jacobs, assistant secretary of State for consular affairs, said Friday.Embassy consular sections relayed those warnings, called “warden messages” through pre-organized phone trees or by actually knocking on doors, she said. Later, embassies began sending mass emails to Americans who had registered with them, but those emails usually reached only a handful of citizens living or traveling in those countries.

Most Facebook users get more from their “friends” on the social network than they give to their friends, according to a first-of-its-kind study released Friday by the Pew Internet and American Life Project.During a typical month on Facebook, 40 percent of its members will make a friend request, yet 63 percent of them will receive such a request, according to the study which, for the first time, compares Facebook server log information with survey data to mine information about Facebook friendship networks.

And the new findings show that over a one-month period:
- 40% of Facebook users in our sample made a friend request, but 63% received at least one request
- Users in our sample pressed the like button next to friends’ content an average of 14 times, but had their content “liked” an average of 20 times
- Users sent 9 personal messages, but received 12
- 12% of users tagged a friend in a photo, but 35% were themselves tagged in a photo
“The explanation for this pattern is fascinating for a couple of reasons,” noted Prof. Keith Hampton, the lead author of the Pew Internet report, Why most Facebook users get more than they give. “First, it turns out there are segments of Facebook power users who contribute much more content than the typical user. Most Facebook users are moderately active over a one-month time period, so highly active power users skew the average. Second, these power users constitute about 20%-30% of Facebook users, but the striking thing is that there are different power users depending on the activity in question. One group of power users dominates friending activity. Another dominates ‘liking’ activity. And yet another dominates photo tagging.”
