Social Bookmarking
Social Bookmarking is a really good way of marking the interesting things you find on the web and sharing them with others.
You bookmark your favourites to the web so that if and when you upgrade your laptop or use another device you can easily access the sites you wish to revisit.
For example here are my Delicious bookmarks that are available for everyone in my Personal Learning Network to use and share.

Another good reason to use social bookmarks is so that you multiple tag your bookmarks into a variety of categories.
Get your Diigo account. I save to Diigo but it also auto-saves to Delicious so I get a good back up.
For both I put a bookmarklet on my Bookmarks bar so I can easily bookmark and tag new links as I come across them.
