Busy.org is definitely one of the best apps in the steem blockchain. Aside from what mentioned in the article, you can also get an upvote from @busy for your post. So there's another reason to use Busy.org though one need certain number of followers and vest to get that upvote. But if you're an active author it's not difficult at all. As a constant user, I highly recommend using Busy.org. Thanks for the interesting article @fisteganos
