This smells like a PR piece. No real content and the interviewer only asked 4 questions. No discussion of what the semantic web actually _is_ or how it works to make data interoperable. I kept waiting for the good part...
I wish more projects were lead by such ernest teams.
Their architecture isn't leaning the direction I'm biased towards (it is more federated than decentralized) but they're honest people trying hard to make the web a better place, and need to be applauded.
