The great thing about miners is that they don't need to care about Spreadcoin's future.
It's irrelevant whether they care or not.  
Miners gonna mine, and it's not our job to police their motivations (as georgem would say).
Instead we should care about making their job easy.
(in a chat georgem told me that's what the spread miner will be all about.
Not sure where he is going with that, but we'll see.)

Spreadcoin creates 1440 blocks a day on average.
Georgem made a few calculations about that:
Even if you had a mining cartel that voted 0% all the time,
you would just need 1 rogue miner that mines 1 block a day and votes 100%
to move the SN reward quite considerably in favour of SN.

So having a rogue miner works both ways.
Also, don't forget that mining is about chance.
Someone could have 100 times more hardware than a small guy,
but that small guy might have more luck.

AFAIK, the greatest thing about miner voting is that SN operators are incentivised to mine themselves,
and be it just one block a day.

As a solo mining coin it is essential to get as many people as possible to mine.

How hard can it be to mine just 1 of 1440 blocks?
I think that's a pretty reasonable goal.
