The point is not to write reports for writing reports, but mainly to answer a demand from the community. People are confused about the choice of the voting strengths and we want to fill this gap. As this requires more work from the curators, we propose to incentive them with a report-upvote. On the other hand, having reports being an open door to discussions is a good idea.
P.S. I must start using steemstem.io - it is so easy to find posts with it and it is great for reading but somehow when I post I do it on steemit : / must change that activity.
I still need to improve this but time is limited... ;)
