dst. I'm not sure if both these you's are directed at me, but I'll reply as if they are.
No, I don't deny access to research information to anyone. When it comes to "trading" information, there is always something that I would consider a reasonable trade. What I get in return doesn't have to be related to said information, it doesn't have to be of same "worth". Sometimes there isn't even an apparent causal relation, if you get my meaning. It can be anything really. A good joke, answering a random question, some funny rp or just being interested. "tit for tat" in the broadest sense. So, if I can, I'll happily point out something that struck me as interesting in regard to the topic at hand. Or, if I can't, (which happens more frequently) point to someone who can.
But as I said before, I see no point in spoon feeding every observation someone might make while researching something. I think its better if some effort is put into it. "the journey being more important than the destination" and all that.
As to bragging or acting snobbish about supposed "knowledge" one might have. I don't think I ever done that. Even if i was inclined to, I don't "know" much anyway. I agree with most of what you say about that. To quote one of my favorite authors "Selling the sizzle is well and good. But at some point you have to produce the sausage"
