Hi! As I know that when you submit your sites to social bookmarking sites, you don't notice that there are two sections in social bookmarking: upcoming section and published section. Usually, when you submit your site to those social bookmarking, your sites will listed into upcoming section; so it is not counted as backlinks. Here I collected some good social bookmarking sites; you can use those sites for submitting. And also get nice backlinks for your site because those sites approve your links immediately.
