Today I share my initial 5 minutes and come up with a "Meh.' It did turn me on to some new blogs, and I found some interesting articles. For me it would be great if it integrated with bufferapp.com You can tie it into your twitter, facebook, and linked in profiles. If you're stuggling to find content, this might be a decent tool (bufferapp.com also provides suggestions which I find good). The pricing starts at free and then goes to $9, $9 and up. 
If I were sway I would have a 15 day trial using all the features that goes back to free if I don't subscribe.
