Likewise, you will also be able to see what your friends have +1 and downloaded.
There’s more! Google also gives suggestions for people to follow, and other content recommendations that you might like. You’ll also get recommendations “From familiar faces,” and see who’s making the recommendation, so you know who to give a hard time if something suspect shows up.
