Every time I see great web design - from a button to a complete landing page - I want to archive it in order to look at it later and receive inspiration from it when I design myself.

I started using bookmarks for this, but it has become to much to handle and pages vanish now and then. I tried Kippt which is awesome for saving screenshots from Dribbble, but not so good for actual web pages.

How do you archive inspiring design?

EDIT: Of course it should be really easy to browse, via tags and colour.
