Agree 100% with you. I regularly upvote minnows just for the sake of distributing the wealth on Steem. More whales need to realize that the strength and value of a network, or token/currency for that matter, is strongly correlated to how well the wealth is distributed on the said network, and how certain positive network reinforcing behaviors are incentivized.
Regarding the voting power allocation, your account needs to have over ~500 Steem Power in it in order to have the voting strength slider appear.
Gave your comment a 100% upvote to help out :)
Cheers!
LOL that's why I don't know how to do it, makes sense. Thanks for the upvote. I just hope that one day steem becomes more content driven, that way it can eventually take on the likes of YouTube.
