As I said months ago: IF Steemians wish to increase the value of their Steem by making Steemit more attractive to advertisers, even if it means a little ad in the sidebar - its frequency relative to competing ads proportional to the amount of @null promotion they received, for example – then this suggestion should absolutely be implemented. Promotion burns STEEM, making it more valuable; so promotion should be incentivised by actually displaying the ads, not hiding them on a page rarely anyone clicks on.
My first resteem!
RE: IMPROVING POST PROMOTION: Move 'promoted' posts to a vertical sidebar - so that they get more views.
