Hi, I am the creator. You can also slide through time by using Shift + Mouse wheel. I works pretty well on Android devices (not tested in iOS). Hope you guys like it.
This is awesome. You could also add in the HN time frame to make it easier to see where in the past you are (the bit below each HN post that says "30 minutes ago, or 2 days ago"). Is there a way to just see Ask HN posts? One of the most annoying things about that section is that it's not in chronological order.
The date is the in the right side (with hour and everything)
Cool! It maybe useful in those times when I miss a day or two of updates.
Would be awesome to have a Mail.app-like link previewer in an overlay.
