Works, but semi problematic – Hacker News (YC) Review

It's great that they enable commenting and login, but there are some significant flaws to usability: 1. Posting a comment - your comment won't show. 2. Swipe "back" won't actually navigate back regularly - the card you're swiping will usually just fall back into place, so you get in the habit of using the back button in the menu bar.
