Often, when answering clinical questions I look for background on Google. Answers.com might be a useful place to look. I have a slight concern about bias creeping in as it’s not clear how they create their answer. For instance they (answers.com) may say that drug X is useful which might then cloud my judgement. The fact that answers.com may have obtained their answer from the pharma company responsible for the drug is initially hidden.

Transparency seems to be the key.
