I created an account using delicious com and it is so easy to maintain your favorites using this. The beauty of this is that you can save bookmarks and access it online whenever you need them. There are also addons provided by IE as well as other browsers from where you can directly store items added to your favorites under delicious account. You can also at any time import / export all your entries maintained under this account. You can also categorize links by giving tags just to add more information to the link.
Create your account using http://delicious.com and you can access browser addons at the following link http://delicious.com/help/tools
I find it an easy and efficient way to bookmark all useful links and access it based on my needs.
Note :: Delicious is existing since long time...now a days the same feature is also available via Google bookmarks.
