This video about @steem-ua , completely nails its fundamental concepts:

• instead of trying to (only) use promotional tools on a per-post basis to acquire visibility per post, @steem-ua incentivizes organical account growth over time
• by publishing both quality content (about which topics is irrelevant for that matter) and engaging with the community, everyone can build a real following that steadily supports you over time, rather than "going for quick wins"

So choosing to work with and supporting @steem-ua both by delegating to it as well as staying active aligning with its core concepts, in essence boils down to a choice:

If you believe in organical growth, both at the individual account level as well as on the collective platform level, then @steem-ua is right for you.
