linkfriend's goal is to support distribution of link lists over p2p protocols like Dat, but so far that has been too labor-intensive for me to tackle. once you can distribute link lists and index them, you will be able to use the search feature like a kind of mini-search engine for your corner of the web. i hope someday to deliver that possibility :)

@garbados oh that's like the old imageboard and, i think, some forum tag systems! cool that you got a typeahead to integrate with that
@garbados that sounds amazing!!!
