First, I disagree with your assessment of quality "now" vs "then", especially if we're talking about the trending page.

I think you're missing the key point of Kevin's post and my earlier one: the current 75/25 split encourages self-voting of nearly contentless posts over voting for quality posts written by others. The idea behind increasing rewards for curation is to reward voters who vote on quality posts (by which they gain curation rewards) rather than just voting for their own posts or their socket puppet posts (by which they gain author rewards).

The idea is to change the economic incentives to cause voters to behave in a way that better content rises to the top. At 75/25 the economics are totally weighted in favor of self-voters. If you follow that out to its long-term end, the self-voters end up with all the coin.

As far as upsetting bloggers, I believe the final result will be to make them happier (especially if they are good bloggers, as the change in voting will reward "better" content more than "crap" content). The primary driver for higher rewards for both authors and curators is a higher Steem price. Anything we can do that moves the price of Steem higher benefits everyone in the Steem community. Having Steem work properly as a efficient content curator will make the coin more attractive. The current self-voting issues are a big black eye for the coin.
