HN is all about discussion of existing content. It is simply a bad form to go to discussion of "blockchan for big banks" article and start talking about "blockchain for ad networks". Yes, maybe someone out there is making something where blockchain is genuinely a right technology; if you find such a project, submit it to HN and there may be actual positive comments on the blockchain idea. Or even better: write a blog post about real-life problems which are best being solved by the bitcoin blockchain, and submit it. I am sure people will read it with interest! (I am not being sarcastic here -- I am genuinely interested about useful bitcoin applications)
