I only resteem when either request. When it is a post that is on trending or hot I do not resteem. Also I avoid resteeming in general because the stories can be found as long as I have a short list of memebers I follow.
I think way back in the beginning when I started on steemit I was resteeming a lot but got overwhelmed by the amount of resteems on my own blog that I did not have my own content easily found on my blog page. Thanks.
