It adds more possibilities and that's good. Whale can decide support some article this way. Also it can bring Ads (which is not good) but on the other hand can bring more investors and paid content providers and support Steem price and bring new users.

As an opportunity - yes, it's good. But only in theory. Not in practice. Minnow will spend the last penny to promote - but it does not work. Redistribution of coins will not be. And Steemit system will not stronger. 100 people have hold 90% of the entire power system.

And only they can change something. And no promotion without result.
Who have read your post with the promotion? This same users as without promotion. The number of readings has not increased.

I don't think so. Look at this. You write some super-content article. Right now only several people will able to see your post and you will receive let's say 1.4$ with 25 upvotes. You have two possibilities:

  • featuring
  • promoting

Featuring is for free but you need to ask some whale and it's not sure if or when he will publish it.
Or you can invest 70 USD and promote your content because you are 100% sure it's best article people have seen.

If you're right and people will like it you will not get 1.4$ but you can get 1400$ and 200 upvotes or more just because you've invested just 70 USD. More risk, more reward and supportive for distributon.

Effect for Steemit is also positive because those 70 SD burned will never push Steem price down.

You're right that for better redistribution this feature doesn't bring very significant impact. But I don't think it was a main purpose when designed.
