I have shared my posts on Twitter on a few occasion but I very few followers.
Yeah, too many delegations to big curation projects is a bit of a problem because not too many people have time to consume an awful lot of content.
For a better distribution of votes, I think it would be useful to have the front ends develop better algorithmic feeds with notifications to motivate us to spend more time on them. When you don't have to go looking for posts interesting to you, you also more likely to upvote them.
Content discovery is still lacking on Hive. That is one reason I do #FollowFriday posts. We can each do our bit to help with that.
