Welcome to the Q&A Forum

Hi Stevene, OpenSiteExplorer - which is powered by Linkscape - is only updated around once a month. So there is some delay between getting links and these links being crawled by SEOmoz. Furthermore, SEOmoz does not cral the web as deep as Google. Low quality pages (and good pages with very few good links) are not necessarily going to show up in OpenSiteExplorer. You can see the update calender here: http://apiwiki.seomoz.org/w/page/25141119/Linkscape Schedule
