Great post @brandonfrye about MinnowBooster.
I never knew that how beneficial services it offers. You've covered 6 services and exactly the number 7 service is about getting notification. As you said you can get the Notifications with the Steemify app and Ginabot is also good for this purpose.
I like the idea of lease steem power and sell your vote.
By the way, this Minnowbooter post is so informative and I learnt a lot.
Thanks brandon.
