I'll copy a comment of mine I posted to a blog post of @whatsup's that discussed this proposal. The quote is @whatsup talking.
Let' build communities and SMTs and attract new users, let's not promise them riches, or content discovery, let's tell them to build a social platform in which they can have partial ownership.
This.
I agree on any tinkering with the reward distribution math almost certainly not helping if the goal is to improve content discovery or stake distribution. Projects like @ocdb are much better at stake distribution. It all comes down to finding an acceptable compromise between rewarding stakeholders and helping newbies grow in order to make the DPoS consensus mechanism more secure. Judging by the 4.1 million SP delegated to @ocdb, a lot of stakeholders think getting 90% as much as by self-voting is enough and giving up for 10% to altruistically further the common good is ok.
