Delicious is shutting down and here are few Delicious alternatives we recommend
Google Bookmarks – a much better alternative and will remain alive.
Diigo – Diggo is a web highlighter and bookmark tool.
Redux – Redux helps you find videos, photos, and web sites recommended by others. Strongly recommended for those who dive into a lot of rich media content.
As far as our recommendation is concerned, we suggest you to look at Redux (for its discovery) and Google Bookmarks.
