I don’t understand the reasoning behind this move. Sure, I get that it’s ‘cool’- Digg just has Twitter/Facebook/etc envy.
Digg used to be a place for finding crowd sourced news (or, more recently, lolcats). Now, it will be merely yet another way to share links with your friends. I get that enough on other sites (Facebook, Twitter, Delicious, Buzz, etc). In order to get any value, you will need to be following a large number of diverse and interesting people who post cool and relevant links. Prior to the changes, you merely had to type in digg.com in order to see what the “world” found interesting.
Digg had a brilliant concept- make the users the editors. When it started, it was great- it had relevant and timely tech and political news. As it grew, they found themselves victims of catering to the lowest common denominator (which equates to funny pictures, it seems). Rather than use v4 to figure out a way to change this (maybe similar to Reddits’ subreddits?), they created a Digg-styled Facebook clone.
Yes, Top News is still there. However, it’s been relegated to a tab.
I wish Digg the best, however I don’t see myself using it if I need to follow and share in order to derive value from the site. It’s unfortunately- Digg has always been a quality site (in terms of software and vision, if not content).
