I tried it for a while, but it is mostly just other users bombarding you with friend requests. There doesn't seem to be anyone reading the content, just users begging for clicks. When someone clicks on your content, you get a few pennies. So other users click on your content and you click on theirs. In my opinion it is a huge waste of time.
