I increasingly just use google to search sites I already know have better content than the web at large, since it so often feels like it sucks for any depth of information. Want to get in touch with someone? name job site:linkedin.com. Want to find how to solve a tech issue? "issue" site:stackoverflow.com, and so on. Google's search of sites like this is pretty good (although the recency working well would be really good... but perhaps impossible to solve well), and often better than in site search. But that + very basic fact finding "how much is a lb in kg", "where is restaurant X" are pretty much all I feel it's good for. Then again, I guess it's not supposed to be an encyclopaedia (or it can be, site:wikipedia.org!)
