Social bookmarking continues to be one of the driving forces of this evolving web, and as we forge ahead towards the semantic web (otherwise dubbed Web 3.0) it will continue to play an important role and prove an invaluable resource for independent publishers, businesses and even casual web surfers.
Social bookmarking is all about labeling the web, making it easier to find the content that you're looking for by passing on what you've found. The labels applied to web sites are commonly known as tags, and over time a kind of taxonomy grows, whereby persistent tags help information to be aggregated and mined for information. Where a taxonomy was, however, the product of specialists carefully categorizing items within their area of specialism, social bookmarking produces instead what has been termed a folksonomy.
