So you've started a Hangout on Google+ with some pals. Now what? Are you just going to sit around and talk? Thanks to some new additions to the social network, you don't have to rely solely on your conversational skills anymore. The software company announced today the addition of a number of apps to the Facebook competitor, which should make your Hangout time all the more riveting. Now you and a few close friends can play poker and pop culture trivia, add mustaches and glasses to one another, collaboratively doodle and share presentations on the service. Google+ also announced today that it has taken its Hangouts API out of preview, letting developers share the fruit of their work with the rest of the site's fake facial hair-sporting community.
