If you don't know it, Clipboard.com is a free online service that lets you pin things you find around the web on boards much like Pinterest does.
Where it excels over Pinterest is in letting you pin live web pages on your boards so that you can interact with them there, instead of being limited to individual images and videos like Pinterest.
It also defaults to making your boards private as well as letting you share them with just a defined group of collaborators. Because of this and fast searching and tagging, and summary list views of clips, it also serves to replace traditional bookmarking tools like delicious.
I made this app because I like the service so much. It has become a core part of what I think of as my browsing/reading/remembering workflow, spanning my laptop, phone, and tablet alongside Pocket, my web browser, and news readers. I strongly recommend you give it a try.
