Has it ever happened to you that as a webmaster, you change the design on your site and your readers hate it so much, they make life hell for you. Kevin Rose is in a similar situation right now because his Digg redesign is firing back on him. It has been quite some time now and Digg is still flooding with Reddit news on the front page.
The new submission system on Digg encourages users to submit their own content and this is saturating Digg just as it was earlier. Digg is notorious for being full of spammers and the submission system on site is in favor of big players like Engadget and CNN.
Funnily enough, the Reddit posts are submitted by the same auto-submission feature introduced in the new version of Digg. Now, as pointed out by many, it is not unusual for a site to get some initial resistance but this is massive revolt from users who are up-voting Reddit posts madly.
Digg is in trouble and it needs to respond fast to retain its dedicated users. People already hate the new but the defacing is what is more worrisome.
