Social bookmarking is a great SEO tool for a number of reasons. The first is that it creates additional inbound links to your content, which is always a good way to gain the attention of search engine bots and increase your page ranking.
Secondly, social bookmarking and news aggregation sites are very popular, especially with the younger generation of internet-philes who are more comfortable receiving news from an online site than by watching television or reading the newspaper. Subscribing to an RSS feed for an aggregation site is a virtually effortless way to read about the latest topics of interest.
