Hmm, no offense to the idea as I'm sure he had the best intentions in mind but it seems quite easily gamed by bots that didn't really read it. I prefer genuine comments like these instead. :D

and yeah I'm sure many don't have much to say about their resteem, I've also been thinking about a "note" system that next to the resteemed by user shows a note that user left for like "hey guys check this new dapp out, really cool" or "easy way to get a nice airdrop in here", etc. That note could then be a comment that exists somewhere and can receive votes.
