Curation Trails are a very interesting mechanic for the Steem blockchain: You can follow a trail and automatically upvote all the posts the trail upvotes. This helps to spread your votes and earn more curation rewards. And you can support the cause of a trail you like.
To create and follow a curation trail you can use the open source software SteemAuto from the developer @mahdiyari. In the video below you learn how. keep in mind that if you follow a trail that it will burn your voting power according to the activity of the curator as well as your settings.
