Gmail's smart labels are the best way to filter your email so that you only get the content you want front and centre. Now, there is also a handy new label that sticks all your social network messages in one place.
In order to use the new smart label, you first have to enable it in Gmail Labs. Head into your Gmail settings menu, click the Labs tab and enable "Smart Labels". Now, all your messages from social networks such as Twitter, Facebook, Google+ and Quora will be filtered into their own "Social Updates" label.
