Establish your expertise by bookmarking sites on a particular topic and utilizing the same keywords each time. By doing this, people will start to follow your stuff and eventually you can incorporate (from time to time) your own content.
Use it to obtain information about competitors in your industry. Think about it, someone has already gone to the trouble of bookmarking it and tagging it for you, all you need to do is read it. It’s like going to the library and reading a catalog about your industry and competitors.
Showcase your content with others. Delicious.com has a new feature called Stacks,which are equivalent to categories. You can name a stack anything you like and then share it with your newsletter list, your friends, colleagues, etc.Some social media strategists will tell you to bookmark all of your content, some will tell you to be a bit more conservative and only bookmark the important stuff that delivers value. But stacks can be all about your own content. For example, if you sell real estate and have a blog giving tips and tricks, then you can create a Real Estate stack called “Tips and Tricks for the Home Owner” and it can consist of all of your tips & tricks blogs.
