Great post! I followed you, now check out my...just kidding.
As someone who has spent some time putting together a few posts that I was sure would trend and ended up going nowhere, I think your strategy is spot on.
Genuine enthusiasm in other people's material will end up with those people reciprocating. I've been on here a few months, and I've realized that my participation in other people's content has been relatively minimal compared to what it could/should be.
I'm making it a goal to curate and respond to posts more than creating original content, at least for a few weeks.
