Well opted topic. Resteeming, as of my experience, is not a good way of publicising content.
Initially even mentions were useless for me but after coming in touch with steemit alternatives like busy.org and partiko. You can catch hold of every mention.
But the problem is, not everybody is ready to go to these alternatives. Most starters stick on to steemit. Mentions will be a good way to publicise content if steemit starts giving notifications of mentions.
