Hi Kevinwong, I'm so glad that you raised up this concern,

In my ideal Steemit world, upvotes go to good quality content. In our current Steemit world, this is far from the case and it is basically just about who you know (or better yet: who knows you) and how rich you are in your Steem Power.

I wrote about it few months ego . I feel the older minnows are being left out in the cold in favor of upvoting newbies for being now. This frustrates me, because I see the amount of upvotes declining. This has led me to upvote some of my own, longer comments, to make sure I atleast earn just a little bit still. I don't particularly like it, but Steemit isn't fair anyway, so sometimes I just can't care too much anymore...
