Keeeb is a handy bookmarklet and web service that stores your web clippings into an easy-to-organise Pinterest-like page.
Once you create an account and install the bookmarklet into your menubar, you're ready to go. If you see something you want to save on a website, just click the bookmarklet and start gathering your content by clicking on photos or highlighting text. Each selection will give you a small popup to save the content to Keeeb, and a dropdown menu to select the page you want to save it to.
When it comes time to review your saved content, open up your pages on Keeeb's website, and go nuts by rearranging the panels and adding comments to your heart's content. Your pages are private by default, but you can share them to your social networks with buttons at the top of the page. Keeeb's design is Pinterest-like, and very nice to look at, so this could be a cool way to share bundles of links and photos with your friends.
The concept is pretty similar to previously mentioned Dragdis, but it works in any desktop browser through a bookmarklet, and stays completely out of your way when you don't want it around. It's certainly not as powerful as something like Evernote, and I wouldn't trust it with really important data, but for quick research projects or for a semi-private pin board of cool photos, Keeeb is definitely worth adding to your menubar.
