Ya, well I like this thread, it's given me a lot more input into the folks that post here regularly. Over the years, no one seems to want to put their age in the statistics file and admit to what age they are but with these recent posts it starts to become increasingly clear that we're all the same relative age group, plus or minus some small multiple and you can't hide from age.
So why does that make a difference? The number one rule in communications is "know your audience". Up until now, I didn't know who I was talking to, an experienced person, an unexperienced person or a professional person. That determines your delivery and how you frame stuff so that folks at all levels of competency understand things equally. Explaining it is the thing and if you can't explain it thoroughly, why waste your time and energy that will go nowhere?
