I'm not sure if I understand what curating means here.

I usually resteem a few posts for each of mine. So if i post in sunthursday, I will find a few I like and resteem those and possibly comment and/or upvote. Is that it? or is there something else?

I notice few people resteeming much and lots of people with only their own content on their feed. I also resteem the good "how to" posts I find in my never ending search for understanding here and the main posts of challenges I enter usually.
