Edshelf one of my long time favorite sites for curating the web has just come out w/ some noteworthy updates.
A user can now rearrange their collection simply by clicking the edit button and then drag-n-drop their tools icon in the order they want it in (think the way a pin is rearranged in Pinterest). Also, a person can add "tags' to their collections which is a ideal for organizing and curating a list. Another neat feature is the ability to filter your collections through these "tags". Finally, a user now has the ability to add notes to a tool and either set it to public/private.
I highly recommend checking out Edshelf by clicking here!!!
