I've used this feature a couple times now. I think it has great potential to increase the visibility of under-appreciated posts, but I really don't like how resteemed posts show up in your blog. I want my blog to be full of my content, not everyone else's (that's what my feed is for). I also think the resteem button needs an "are you sure?" dialog. I already pressed it once by mistake, so now there's a post sitting in my blog that doesn't have anything to do with the general theme of the posts I write. And no way to remove it, argh.
unresteem? Might be good to open it as an issue on github though.
