Delicious didn't fail, it was a successful startup that stayed relevant for years after a decent acquisition, before fading away. I can think of a bunch of reasons why it's no longer relevant: - Yahoo and many of their properties stagnated - mobile browsers didn't support bookmarklets and extensions that made Delicious so easy - Facebook and Twitter became more convenient places for sharing links - browsers became "good enough" for archiving links because of syncing and cross-device access
