The graph shows that search volume for digg (in light blue) increases very much until 2007. In fact you can see that the term digg passes slashdot (yellow) in popularity in the beginning of 2006. The letter A marks the digg revolt. This was when Digg, prompted by legal threats, took down a news with more than 10,000 votes about the decryption of HD-DVDs. Because of massive protests they put the news on-line again. Since then, since May 2007, search volume for digg has been going down slowly but steadily, while competitors such as reddit (in red), and stumbleupon (green) have been catching up.
Many people go to webpages searching for the name of the webpage, so search volume for the name of the webpage could be indicative of its visitor statistics. On the other side, many regular visitors may have bookmarked the page or may have learned it URL (it's short enough), so search statistics alone may just as well be misleading.
However, looking at Alexa pageview statistics for 2009 for digg.com sems to confirm the impression that digg does not grow that much anymore. See alexa statistics for digg.com in the image below.
Unfortunately Alexa.com and compete.com do provide statistics only for time periods until two years and a half.
