Thanks for your feedback. Idea of the service is to easily save links for later use. There is some hidden tags automatically created when saving a link. ;)

You cannot comment a link but you can edit the title or add tags. I use "note" tag for links that I need to check later. It reminds todos 'cos after I've checked the link I remove it.

The date saved is shown when editing a link. The architecture is quite flat and everyone needs to find what works for them. I hope you could register and test the service yourself. :)
