I think the boost feature should have some sort of random time delay. 

if you boost something, its likely you've just seen it - meaning others are likely to have seen it if you have any significant overlap with your followers. 

Time delayed boost basically functions as taking the note and throwing it in the air until it drops back into someone else's feed - which with a time delay is likely to be a different time zone and therefore increasing your reach. 

 I want a post feature that does something similar for people with sensitive identities. Randomly time every response such that it is impossible to tell where in the solar-system they are posting from by checking timing. 

 Interesting idea. Do you code in JS? Could be a relatively easy addition to a client such as Coracle or my own nostrgrowth.arcmapbtc.com which is based on coracle. This last one allows scheduling of a post but not randomly at this time. Could be a nice feature though. 

 Yes I schedule the repost for a diff time using nostrgrowth.arcmapbtc.com which is a client I built on top of coracle which added this functionality. I just schedule it for the next day so its not immediately.
