This looks very much like the old site del.icio.us (which was bought by yahoo and discarded). Don't bother going there but see [wikipedia][1].
The trick there was that it was originally a "personal bookmarking" service, so there was a selfish reason for individual users to submit + curate links. Search got layered on top later.
