I've only used the resteem option twice.
Once was because it was an interview with me that a person did, so it made sense.
The second one was a post that I was trying to upvote on my mobile device... Next thing I knew, my big finger missed that little button and I had suddenly resteemed that post!

Accidental advertising!

Before, I could handle following almost 500 people, now I feel seriously spammed out.
That's why I am hand-typing in my favorites now just to see what I missed, like this post from you, @bullionstackers.
