Voted for A low feasibility / high impact (upper left corner).
Funding is imo the biggest problem our apps are currently facing. There are cool ideas, people willing to work on them, the technical skills to make them happen, but what is missing is the funding (and stability) which allows developers quit their normal jobs and work on Steem Apps instead
But currently I don't see much willingness from investors to support the apps. Imo the main reasons are 1) the markets 2) still pretty high (but much lower than a year ago) opportunity cost compared to delegating to bidbots.
