diigo social bookmarkingDiigo is fun! It is my absolute favorite. This service has an enormous amount of tools and features — it is more than a bookmarking service, it is a complete tool for online research.

Delicious is owned by Yahoo. It is by far the most popular social bookmarking tool out there, but it is not rich in features. It is easy to use, though, and has a huge community, which makes it a very valuable tool.

Furl

furlFurl is part of the Looksmart family and has been around forever (like Delicious, Furl launched in 2003).

It has a solid security policy (the importance of this has been highlighted after Ma.gnolia crashed and lost most of the boomarks of its users) and advanced sorting, searching and editing tools.

Simpy

simpySimpy is another old-timer in the world of social bookmarking. Unlike Furl , Simpy hasn’t updated its look much. This gives it an odd but cute retro look. This does not compromise ease of use, though.

In addition to storing your bookmarks, Simpy also stores notes. With the Note This! bookmarkletbookmarklet you highlight and save text. Notes are private and each note gets a title and you can add tags to it, just like the bookmarks. When searching, you can choose to search notes or bookmarks — your own or everyone’s.

Both have Firefox add-ons which work a treat. It’s easy to add links on the run. Both work on tags. I particularly like that Diigo lets you save websites as ‘Read later’.

Happy for you to look at my accounts:
