Reminder Bear is a service that lets you create single-use bookmarks. Save a page with the bookmarklet, and Reminder Bear will email it to you a week later. Or you can easily customize your reminder time using the overlay panel. Use Reminder Bear to: a) follow interesting comment threads; b) check websites for updates; and c) clean up your bookmarks folder. Simply check your email and let Reminder Bear do the remembering for you. No lengthy sign-up, just enter your email address to create a bookmarklet.
