People don’t want to see uninteresting replies and casts.

Best way to solve for that is weight historical inbound engagement for a user, i.e. PageRank-like score for every user.

Disproportionally hurts new accounts. Making it harder to get started.

maybe this could be counterbalanced by an algo boost for new accounts with interesting casts?

1) display top-level casts and replies to a subset* of power badge holders

2) if no engagement, display to even fewer pb holders until eventually hiding completely 

3) if engagement, display to more pb holders until eventually giving an algo boost to highly engaging new comers

*could be opt-in & include warps bonus

How do you know what new casts are interesting before they have engagement?

My first thought too
Give new accounts a positive ratio by default, and reduce it if the accounts don't get engagement

Algo boost for new accounts + craft a more engaging onboarding experience to push users to join channels and post in channels. Let each channels decide what is considered HQ and what isn't through community moderation. Weigh that into the algorithm of someone's "rank"
