Popularity always comes at a price. BBC News reports that hackers are increasingly looking to Facebook as a means of harvesting information, with five separate "viral" applications seeking to gather user information under false pretences in the last week.

Do you think Facebook is at risk from the wave of hacking attacks, or is its bigger problem maintaining interest levels among more jaded users? Share your thoughts in the comments.
