Resteems have always shown up on your steem feed, unless you filtered them out.

You can do that here by clicking on the filter button and you will be presented with the exclude reblog option to exclude them from your feed. There are also other filters you can use to mange your feed, favourite authors and lists you can create. I reblogged one of those posts. I guess it's kind of important as a mod in that community. A bit like the reblogs from Whaleshares community:)

All posts you vote on Whaleshares, get reblogged lol
