I have a pligg website and daily i get around 10-15 bookmarking submissions to this website. Code: http://edition.cnn.com/2012/04/26/world/europe/uk-royal-kate-corporate/index.html?hpt=hp_c2 I don't understand why people are bookmarking to cnn website. Can anybody explain. What is the logic in this. My website is not like digg where people save bookmarks and read later. This pligg website is clearly built for spamming own links.
