It's one of the top level comments: http://www.reddit.com/r/AskReddit/comments/tmtd4/what_are_th...

The list at the top of the page is perfunctory, the rest of the top-level comments are meant to add to it.

The Edge is pretty awesome. Eg:

These are links I keep going back to, and have been thinking about for weeks.

I like the edge but there RSS feed is so terrible that I gave up reading it.

Do yourself an enormous favor and subscribe via email. I recognize the friction, and I understand why this may keep Edge from shooting to the top of lists like these. But in terms of actual content it's unparalleled.
