I am an academic quantitative researcher who primarily teaches statistics and quantitative methodology (not in Statistics, though). Even with frequent use of the ignore option here, the signal/noise ratio is too low lately. However, it is like mining low grade ore. The nuggets you find after time are well worth it.
Nebbya great reference to signal/noise ratio. If I may ask, are you in the electronics industry, or an audiophile, or etc? I have a varied technical background, including some electronics. -bbq
