I use Raven every day.
It's a great way to build up some tokens for free. I can choose which posts i want to interact with so I'm not sharing anything that i wouldn't agree with or involving a project i know nothing about.
It's a great tool to guarantee you get eyes on your product/post.
It can help build a following with a target audience as you can set your own criteria.
It can be used to reward your projects community for raiding a post.
It has an easy to manoeuvre UI and easy to claim rewards.
If you use twitter often you may as well check Raven and get paid for it.
