Super cool idea. For my personal use, I'd love if it worked slightly differently, i.e. had the following (additional?) features:

- let me press a button in my browser ("lottery" or "Russian roulette") and just open a random link (from my bookmarks) immediately in the current tab; I'm not interested in emails, but I'm interested in getting inspired sometimes, exactly when I want it and how much I want it :)

- if it could also load bookmarks/favourites from HN & lobste.rs

- as other said, working on Firefox :)
