Comments to resteems would be nice. They would have to be very short, of course.

And yes, resteems are a very underrated tool for curation. Now that 50/50 has been in effect for a couple of weeks, I've resteemed a lot more than before. It is fascinating to observe voting on a post when it is worth pretty high, say $20, and resteeming it after which it goes up to $100 in a matter of a couple of days. Far more often a post will reach its final valuation within 15 minutes to an hour.
