If you find yourself bookmarking things left and right but rarely ever getting back around to looking through your bookmark collection, NetRocket can help you wrangle your bookmark mountain.
NetRocket is a social bookmarking service. Sign up for a free account, place a NetRocket button on your browser toolbar, and you can begin using the service.
Whenever you're on a page you wish to bookmark, click the button and the Add Item dialogue—seen above—will pop up. There you can add tags, categorise the website, flag your bookmark as a private one and assign a schedule to your bookmark.
The default schedule is none, you simply tag and bookmark the site and it's stored away. You can however schedule a review date for the bookmark to remind you to read over it in the future and even make that review date the day the bookmark is purged from your system. Using the purge function, you'll never find yourself with thousands of unused bookmarks and a pile of flagged articles you intend to get around to reading "someday".
NetRocket is a free service and is compatible with all major browsers.
