Social+Bookmarking

I have been using social bookmarking since the 08-09 school year. I introduced it to my students during our research paper unit. Since then I have continued to use it and have been pleased especially with my education diigo friends. I have learned about all kinds of sites dealing with 2.0 tools, learning theory and lesson plans. Recently though, my bookmarked sites have not been adding to my site. It says they are but I can't locate them. . . ? Any suggestions for retrieval would be greatly appreciated!
