On Thursday, April 21, Yahoo announced they will be discontinuing "Yahoo Buzz". This follows a growing list of 1.0 social bookmarking sites which are now stopping operations (Del.icio.us - RIP 12/2010 and Propeller.com - RIP 09/2010 to name a few).
Why is this happening? To quote a comment from the article from DailyBlogTips, "I think Facebook and Twitter are better than all others." I believe they are right. Amazon, in 1998, introduced 1-click buying and subsequently increased revenues because all purchasing barriers had been removed. In comparison, all I have to do on Facebook is "Like" a link (effectively giving it a personal testimonial).
Out with the old and in with the new.
