del.icio.us cached++

https://wordpress.org/plugins/delicious-cached/

del.icio.us cached++ uses the built-in MagpieRSS engine functions to create a list of the latest bookmarks on a del.icio.us account, from its RSS feed, keeping the feed cached in the database.

This plugin respects del.icio.us' ToS and will not to overload the feed with subsequent requests, since the default cache refresh period is 60 minutes.

The plugin is wigdet compatible, and allows multiple widgets with independent options.
