These are not long term solutions because they require the collaboration of the whole community which is almost impossible/ will become impossible.
Here is a comment I wrote under a post of Steem's longterm value by @cryptovestor which addresses the same topic.
As a student who develops bots for Steemit I deeply believe in the long term value of Steem. However, Steemit may be doomed to fail...
We haven't seen much development on Steemit in the last months and the content quality in Hot or Trending is at an all time low. Most social media sites have a "recommended" page that accurately suggests good content.
But we do not have any other way of finding new content besides Hot or Trending. A lot of top ranking witnesses run their own bid based voting bots and therefore I think we can agree that these bots won't disappear over night....
The only other option to find good content is to develop a "recommended" page and I'm almost certain that that will happen. With better content this new site will quickly replace Steemit especially for new users who are just here for reading good content and not for earning money.
Please point out any flaws in my theory!
