My feeling is that people with high SP are generally also the ones with high reputation.
Yeah, that's sometimes true, but I consider my reputation to be rather high, while my SP is very low, despite writing for awhile, and never powering down.
I'll never be able to actually invest my own money into Steemit, because I work for Steemit publishing my content here exclusively. So they already get half my money.
Yet, I'm extremely displeased with my inability to have a useful vote.
I know the whole "your vote isn't worthless, it starts a trail" thing is noble, but there is a clear difference between a whale/tuna, and a minnow, and it's pretty annoying that I only get half the features that Steem offers, and will never be able to afford anything greater, just because the actual amount of money I'd need to invest to get true voting power is ridiculously high.
Any solution?
Unfortunately I don't think there are any easy answers. It's tempting to say "well just make everyone's vote equal", but that introduces its own set of problems (big investors feel cheated + no incentive to actually hold a lot of SP). If only the disparity between the larger & smaller accounts wasn't so vast... the tough question is how can that be solved in a fair way that doesn't give anyone a raw deal.
