It's a good way to have new authors noticed, if you have someone in mind you can submit a post to them as well. Besides the author getting the curation upvote, the person who submitted (curator) receives a reward as well (is Steem). You can go to @curie or in #curie on steemit.chat.
That is very good to know and I wish I'd known about it earlier as there have been a few posts I have come across which I feel deserve more recognition. I will remember this the next time I come across a post I particularly like. :)
