Today at Google I/O 2013, Big G revealed a big redesign for Google+. Starting later today, users will see their content in a multi-column setup fit for any size screen. The home page for G+ now has up to three columns populated with individual cards for posts and pictures, and the social network can intelligently learn the content of those posts and automatically add related hashtags for you. Columns appear or disappear depending upon the size of your screen, and cards can be flipped to reveal editing options, or moved to suit users' aesthetic tastes. Should you have the requisite screen real estate, pictures and videos expand to the width of multiple columns to further provide a more visually pleasing social experience. In order to eliminate clutter, Google + has adopted a familiar looking left-side menu layout that disappears until a hovering cursor (or presumably a swiping finger) reveals it.
Update: You can see the new layout and auto hashtagging in action in the video after the break.
