Over the last year I have gone from a complete sceptic to a vocal advocate of the fast growing micro-blogging service, Twitter. The reason for this conversion is directly related to how I have seen the Twitter service evolve from a distracting playground for narcissism to a powerful and authentic source of crowd-sourced news. At times over the last year, Twitter has arguably rivaled the biggest news and information portal sites in the industry. Further, I would argue that Twitter could soon do what Digg had promised and failed to do years ago, to democratize the news industry.
First off, if you don't use Digg or Twitter here is a quick overview of both.
Digg is a social bookmarking service where members "control the headlines" by promoting their favourite news stories. If a story gets enough votes (called "Diggs") then it makes it to the front page of the Digg.com site, an esteemed honour which can drive significant traffic back to the original content source. The popular content can stay there for as long as it keeps getting "Dug" by the registered Digg
I agree, Twitter is much more immediate in the delivery of information. Your contacts tailor the information flow to topics of their interest, which hopefully are your interests as well.
