I love this concept, its like a power user's knowledge base specifically tailored to consuming large amounts of web content. There are definitely power users and busy people who could benefit from this. However, I think the most difficult thing this project will encounter is making money, because it is too niche to attract a large enough user base to force Google to pay for default status (not willing to switch browsers). I hope that once they roll out their core knowledge base system they pivot to making a cross-platform group of browser extensions/mobile browsers to expand the reach of their service.
