Exactly, cross promote, I've just seen an excellent TED talk here https://steemit.com/life/@connorcranston/best-ted-talk-period-how-to-get-whatever-you-want-in-life and it is a promotion and I feel the better for having seen it.
It made me think of this post again, nothing wrong with promotion, lazy cross posting never gets my vote, mainly because it never gets my attention.
