Support is amazing. I've had personal calls with Saul the CEO. The best feature is the automation which pulls information in from RSS feeds and automates them into tweets WITH graphics / pictures. It's really incredible.
You can automate 25 tweets in less than a minute and schedule to buffer once you've set it up. So you can smash twitter. Then you'll want to use the pinned post or tweet to feature your own content once you're getting lots of profile views.
It has a call to action feature so that any link you share you can put a banner across that website with your call to action and a subscribe button.. it's insane
