This model, as pointed out by myself and @droucil leads to?:
WAY MORE CONTENT THAN READERS CAN DIGEST, and more motivation for posting crap to be waded through and thus tiring to users
So current model may be working for the network at this point, but over time, inflation needs to expand the block supply, and the network requires less content and more engagement to attract curation and engagement per post.
Otherwise it will only be the first 100K users that enjoy most Steemit rewards, and a time rip-off for all other users, faced with more content than they can ever browse through.
Meanwhile: We needed communities to help filter all this content, 6 months ago...
People don't need to view 100% of a sites content. In a day, a year, or ever.
Look at reddit for example.
Btw, I didn't really suggest a "model" as much as a method to get actual traction on one's own profile. They could do my suggestion on SteemIt, inside a community, in MSP, or anywhere else they are able to convert their peers to followers.
See the user I was replying to for the context of my suggestion. (It wasn't exactly related to the top level post content)
