Well, you submit to WW and it gets botted madly. WW links to your sites from four separate pages while a link is new, then drops down to three. Your partner page lists (I think) your 25 most recently accepted links. So each link will slowly slip off of that page as new links are added, but even then, WW continues to link to your sites from a category page and the link's individual "info" page. What I'm trying to say is, trust me - the bots are finding your sites.
