It might surprise you to know that I dont post links to everything either. But if I am quoting something as fact in the manner you do then I go out of my way to try and find a link or a reference otherwise I tell people that it is an opinion (which without a reference is all it is).
I will also state that I am not sure of the facts if Im not.
If you look through some of my posts I also have stated many times that whatever it is I am relating is something that I have read, yes I know about books too. And if I cant remember where I have read it at least I am considerate enough to inform people of that fact.
No one expects you to have a complete reference libary at hand. Same as no one expects you to be able to remember where you have read a single line in a book 20 years ago that has stuck with you.
What is nice is to be able to give people an inkling of where your opinions have seeded. If you dont have a link, be up front about it, dont tell other people to look it up as they are not the ones making the claims, you are.
Also if it comes from a book and you can remember the name of the book well then thats at least a start.
Its not so much 'just' about the research. Its about letting people know where, why and how you formed your opinions, regardless of the subject you have posted about.
Very well said, Hazard. Good advice for all.
