Exactly... there's a special feeling that comes with even a handful of regular followers that comment on your post. There are a lot of quality content out there on hive that dies unseen.
Another big problem is the fact that after the 7-day post time frame, a post literally dies, basically because rewards can no longer come in I suppose. Even some authors might not reply comments once their post is past seven days. The reward system unconsciously makes us "kill-off" old posts.
I believe though that with more popularity for hive, old posts will start to get revisited. On Quora for instance, most of the posts I even read are posts that are years old. Hive I think should be more Quora-like and less Instagram-like (short term post engagement that dies off in a couple of days)
