Under the current system there is a race to be first which results in a random ordering of votes from bots on a post. The order dramatically impacts the profitability of the bot...
Not only the profitability of bots, also low-SP users! (i.e. most users). By the time those 30minutes are over, our weight will be 0 = no payout... Explain to me how low-SP users are not getting screwed here?!
EDIT: at first sight the weight isn't going to 0 after 30min, great! It might be an improvement after all :)
That's said, low-SP users should pay more attention to write something and/or vote organically.
Most low-SP users will never 'organically' catch up with the whales, so they will remain relatively weak.
The only way for them to successfully participate in voting will be to pay hard cash for more SP. Probably this is supposed to create demand for STEEM. Not with me though, at most I'll mine SP but that's it.
I refuse to pay for power others gained by just mining early :)
You can always create content. There's no barrier to entry or accumulation of SP that way ;))
