On the post... Do you see that broken arrow next to the reply button? That is the resteem button. Resteeming throws that post up on your blog for all of your followers to see. If you REALLY like something, you resteem it!

Curating is the process of finding good content and upvoting and resteeming it. Upvoting can get you some tiny curation rewards.... Nothing to write home about....but a nice thank you.

I guess curating can also involve flagging or downvoting copy pastw spam or plagiarism. But no curation rewards...just the warm fuzzy feeling for helping keep steem clean. (Don't flag someone with lots of steem power OR higher Reputation than you.)

Oh....reputation is the number next to your name. It isnt worth money...but if you drop below 25 or below 1 then you become invisible. And so no one will read or upvote your posts.
