Source checks ?

For years now I've been seeing forum signatures with phrases like "no source checks", so when I started the blog I expected loads of readers would email me asking for them. Amazingly even though over ten thousand people have visited the blog, I've only been asked to do five source checks. I've concluded based on this that the typical "no source checks" forum signature is in fact a rather clever reverse psychology technique, either that or my readers are way smarter than average :-)
