Markcase is a simple bookmarking service with an emphasis on privacy. You can be as public or private as you want with your bookmarks. You can control the visibility of your account, your tag bundles and your bookmarks.
Markcase lets you bookmark from the browser without any fuss. The design is simple and lightweight.
Each tag comes with it's own feed. Even if your account is private, you can still subscribe to a tag's private feed.
Markcase supports searching across all your bookmarks.
Group your bookmarks into bundles to keep your bookmarks organised. Don't like sharing your bundles? No problem, they can be set to private as well.
