Perhaps exploring solutions can yield better outcomes if exploring with the ones that will benefit from those solutions. For example, if you are trying to develop agriculture solutions for Africa, a blog post promoted on HN and Angel is unlikely to be read by a subsistence farmer in Africa.

There is a cottage industry of people claiming to do projects to help Africa. With marketing via blog posts geared towards those with access to capital, these projects can be funded. And since it is about Africa, there is less scrutiny about how effective it really is. Superficial facile accolades along with wining and dining at global events can further obfuscate this reality.
