These ones are my favorite---because they help us connect with the audience who doesn't yet understand cryptocurrency but understands that they are being screwed by the current system. This is a great primer for people who are looking for alternatives, while also enabling them to later use the site as a resource for legitimate investments in cryptocurrency that are not outright scams or that could hurt them.
I would prefer to see BM start focusing on technologies he finds promising so we can start using the blog posts to make connections. I know for a fact that if I could go to a certain coin's community and "sharedrop" a positive review on their technology along with the audio-format version, that it would be far more likely that we could bring them in as guest speakers for hangouts, and get them interested in possibly adopting DPoS or finding ways to add new protocol layers to it when needed.
