@timcliff Yeah I've heard that as well, though I imagine posts wouldn't be considered "active" unless they received enough votes to "activate" the post itself. I hope with some of the recent optimizations (moving out of ram to disk, the payout to rewards balances, etc) that a hit like this wouldn't be a reason to deny the change.
There are definitely some potential hurdles/problems, but I think the pros would outweigh the cons and shift the overall dynamic in a positive direction. The life cycle of a blog post is much different than what our payout cycles currently allow and we should try to do something to encourage long term content.
