For a small annual fee, Pinboard can download and store a copy of every page you bookmark, for your own private use.

How does it work?

Each time you save a bookmark, or put something on your toread list, Pinboard will crawl the URL and store a permanent copy of the page to your account.

Interesting… as much as I want to still like Delicious, this is the feature that almost swayed me to move over to Ma.gnolia before their epic fail.

This is a mighty powerful feature.
