How much would you pay to reach out to a stranger on Facebook?

The social networking site said it is testing a plan to charge people $1 to send messages to people outside their network.

Most messages go straight to your inbox.

But there's a second class of messages, including potential spam, that's put in the little-known "other" folder.

The company will now allow people to avoid the dreaded "other" folder and have their messages show up directly in their inbox.

Facebook says this could be helpful for people who want to contact someone about a job and could cut down on spam.
