Cool idea! Do you think you could extend the intervals it sends out emails? I, for one, would really appreciate being able to have a weekly digest of links that I could check out on the weekend instead of a daily email.
I wanted to add that but I didn't have time this weekend. That's actually my biggest feature request from myself :P. I'm super busy over the next couple weeks, but I'll see what I can do to add this, maybe even just a hard coded "Send this only on Friday."
Thanks for checking it out!
