Wall Street Journal incorporates Digg buttons

Per Kevin Rose, now that the Wall Street Journal is providing the public full (free) access to the WSJ’s online articles, the WSJ has started placing Digg buttons at the bottom of their articles.

Digg is a community-based popularity website where news stories, blogs, and websites are submitted by users, and then promoted through a user-based ranking system. Obviously Rupert Murdoch sees greater revenue through Internet users virally promoting the WSJ’s content than charging WSJ subscribers under a closed subscription model.
