Quality content is often very "niche", not to mention subjective.
Niche content will typically languish well beyond the 7 day window before being discovered by other like minded and interested readers (personal experience).
Some quality content may have a very long shelf life, again meaning the 7 day window expires well before it really gains any traction or visibility (the long tail of a viral post). For newcomers and legitimate ardent fans of underwater basket weavers, this can be very demoralizing. Especially when they observe the crazy earnings of some of the high rollers pumping out high volume, short shelf-life drivel (I'm talking about that ugly hajin vs berniesanders thing).
Encouraging niche communities around specialized subjects is going to be essential. Otherwise we're all going to drown in bible quotes, food pics and bot spam.
