In place of Google, StackExchange offers me a place to get helpful (useful) information from real people without having to sift through the world wide web for my morsel of information. I'm curious in knowing, how much has StackExchange (the network of sites) helped you as opposed to other sites you find in a search engine?
On a side note, Community based networks are relatively new. Information is now globally accessible across a wide-base of community sites that you can depend on 86% of the time for accurate information. Unlike Google, where you'll have to spend an hour or 2 to verify a morsel of information you may find on a particular site (years ago). Now however, community sites are starting to boost the Search Engine's ability to offer relevant information.
