Pond Boss Forums INTRO Questions & Observations New Column in Pond Boss

I would like to read article(s) about how the digital age of computers, social media, forums, and such have impacted the fisheries/pond science business activities. Both good and bad. How knowledge and pond management techniques used to be communicated, say 30 years ago, as compared to today. How methods have changed like DO measuring. I'm assuming equipment like a Pro ODO was not around 30 years ago. How was DO measured pond side 30 years ago? The evolution aeration equipment or fish food advancements. Maybe an interview question and answer type format of guys that have been in this business for many years.
