This reminds me of the early internet. Every little site had a "links" page or "friends" or "sister sites" or "blog roll" There were also "web rings" which was a club you could join. You put a widget on your site that would randomly link to other pages that were part of the same web ring (and you'd get back links from other sites). I haven't really seen any of those things in probably 10 or 15 years though.
