An account seems mandatory to even download or use this browser, and that combined with what appears to be a lack of any compelling advantage above the existing mainstream browsers means it probably won't see much adoption. Even the site doesn't have a dedicated features page but simply a carousel that highlights "Links", "Lists" and "Feeds" with very little details, and apart from Feeds, the other two don't seem very interesting or unusual. Oh and lack of tabs is probably not a selling point for the vast majority of users. And no mention of whether it is open source.
