I am a believer in IOTA. But it won't start working properly until it builds a community and gains some trust. And I agree they are not working hard right now to use headstart with "blockless blockchain" (they need to get a new term for this). Their activity from GitHub is weak, and that is why new projects like nano get a lot of space.

Tangles scalability beats blockchain in every aspect.

Most interesting for me is the futuristic thinking and implementing in autonomous vehicles, smart houses, etc.
