With social bookmarking you may very well never get to see backlinks reported and that's because sites like that are mostly nofollow. Social bookmarking is about getting direct traffic and not really for search engine bots to spider, although bookmarks do get crawled (but search engines might not show you that they did).
You must participate in the social site in order to get some kind of following from the people who use the site and also get a good reputation there. The key is to get people interested in what you have to say so that they will be likely to look at the pages that you bookmarked.
