I was thinking of buying some Steem myself and powering up as it seems like that is the only way to get noticed and upvoted, but decided against it.
I agree with most of your points. I think the idea of Steemit is great, but until they employ some kind of quality filter you are going to see some of the great content written my minnows go under the radar and not be rewarded. At the same time you are going to see really lazy, one sentence posts or unfunny memes being heavily rewarded just because they are written by whales.
The idea of multiple accounts where whales delegate their SP to another of their accounts and then upvote their original account also needs to be addressed. That should be easily fixed because you can see where people have been sending SP to their multiple accounts and then upvoting their original account from these multiple accounts and making a shit load of money by curation.
