Just because Yahoo's expectation$ weren't met doesn't mean delicious didn't live up to its potential. Many people got accustomed to use it as a search engine and it fulfilled its purpose quite nicely. Imagine if facebook couldn't figure out a way to make money, would it then be considered a failure even though millions of people find it useful?

Depends on who you are. To the investors, that would be a failure. To the people that find it useful, it wouldn't be a failure until it disappeared or otherwise ceased to be of use.
