I have been wandering if there are also social bookmarks for sports that one can use to optimize articles on sports?
most social bookmarkings are in general.. so everyone can share almost anything.. as well as articles..
every of bookmarking websites have sports category to bookmark your links like digg, stumbleupon, mixx etc
I own a sports forum and we allow users to post their articles. You can post the article with your website address. Hope that helps.
