Blocktrades explained it that 24 hours is enough for curators to discover new content.
That's a bit subjective and definitely not always the case, especially on weekends... It should be chilled surfing on HIVE and not pressure to catch everything in the last 24 hours...
I tend to agree. On the other hand, I understand his position that early curators who find and bring posts to the spotlight should have a bonus. But you have much more experience with this, and if you say 24h is not enough, then we may be not the only ones who find it insufficient.
