Here is an example of some of the big benefits of using web 2.0 and Social Book Marking and Linking. One of the great ways you can use the various social bookmarking sites like del.icio.us and ask.com, backflip .com or many of the other ones is as follows.
Suppose you’re an educator or teacher – you could reference a number of resources around a specific topic on a site like mystuff.ask.com and then provide your students that specific page to do their reference study.
Or suppose you’re doing research on a specific topic, when you find valuable pages around that topic you could add and categorize them all together on a site like mystuff.ask.com for easy retrieval.
A network marketer could use one of these sites to provide a list of all the valuable websites that support his business to make it easy to provide to a new distributor.
I think you’ll find these sites like mystuff.ask.com and others to be very valuable and a time saver.
