→ Daniel Jalkut’s Review of Instapaper Archiving Siracusa’s Mountain Lion Review

But how did it happen so quickly? Does Marco special-case certain popular pages like this in an effort to boost perceived performance? Or perhaps one of the subtle improvements over the years has been some kind of automatic server-side de-duping of archives. This would save Marco a bunch of space on his servers while also improving performance for users.

These meta-reviews of Siracusa’s review are awesome.
