Promote is apparently giving your article more promenance on the ecency website, but I didn't notice any good effects from this.
Boost however is pretty good and gives a nice upvote on an article of your choice.
You only get the points if you use the ecency front end, so its worth to make sure you do at least 10+ comments on ecency each day. !CTP
Well in that case lets leave another and with promote I think my articles have a bigger chance to get voted as a part of Encouragement program. But that might be a coincidence
you have been hitting it out of the park with your articles. keep up the good work!
