We need to convince network participants that even staking their 1000 GRC balance is worth it as it disrupts larger stakeholders. Even though at an individual level this seems insignificant, a large number of small stakeholders would have the desired effect of breaking up larger stakeholders rewards. Perhaps publishing stats on it would help.
I also still think PoST is worth a review as if I understand it correctly, smaller holders chances of stake are improved (needs a smarter brain than mine to confirm).
