I like what you think and care about, the right question is do really steemit team care about this? Is their main goal to grow Steemit and Steem blockchain at all? Once this question is yes, that I am sure it is worth it to discuss and find solution for. Marketing agencies would be a great solution for bringing popularity to Steem, but I believe PR wouldn't be enough without having new updates and changes to Steemit. Since I started more than two years ago, nothing changed so far besides the Featured system and Ads shown into Steemit.
