Pinboard is a social bookmarking service which allows you to easily save and organize any number of links, with no limits on text descriptions. Pinboard is characterized by having a no-frills, simple interface, by being very speedy and reliable and by being able to import, sync and export all of your links easily.

Pinboard integrates also a powerful web caching and indexing feature available to "pro" accounts ($25/year) which allows you to keep a full cached and searchable copy of any bookmark you save.

Advanced edit tagging, filtering and bundling features make it easy to oganize and find links even inside very large collections.

Links saved can be set to be public or private.

All of the bookmarks saved inside Pinboard can be easily exported in a standard file format. A set of basic APIs is also available.

You can import all your existing bookmarks from Delicious, Google Bookmarks, Diigo, Firefox, Safari, and many other sources by following the instructions on the howto page.

A very useful feature called Tab Sets allows to quickly save all of your currently open browser tabs to Pinboard having the unique advantage of being able to re-open them even if you're on another machine or in a different browser. 

N.B.: The site has a unique and now proven business model and is entirely self-funded. Ad-free.

My comment: Excellent bookmarking service for anyone in need of a no-frill, reliable and fast tool. The archiving feature is particularly valuable as well as the auto-syncing with multiple services (Instapaper, Read It Later, Twitter. Delicious).

The service has a one-time fee of around $10.
