Regarding Critical flaw c (Chaos in tags/topics) - could this not be handled by the free market and what the free market decides? For instance, on reddit, there is the 'bitcoin' subreddit and also the 'btc' subreddit and both can coexist on the same platform albeit with a different focus, mindset, tone, audience, etc. The free market can decide which topic/tag they prefer and that they want to give attention to.
