I would like to call upon that general rule of "no spoilers" that MD holds. If it wasn't present, I would like to share a lot of my thoughts on the open forum.
Take a look on Mur's Show of Force.
This is just an example of how in MD research conclusions should be shared carefully.
One more proof to it - research clues, they are not openly distributed, you have to invest points to get them, a lot of effort.
There is one more thing to it. If you openly share your conclusions, you 'violate' opportunity of others to understand a said subject, and to understand is a delicate process, it has to be bent individually - I personally am not too trustful of my teaching skills, maybe I will earn that trait in time, which is the reason I am not that active in sharing thoughts, I simply don't know how to do it appropriately.
Regarding you saying newbies are 'banned' from such knowledge because of our system - I beg to differ. There are many examples of players who quickly got their way into research, faster and with more ease than some veterans that were there trying to do the same for years (not that I try to insult anyone, I'm making a point that the system is not anti-newb constructed).
I'll pick out Ravenstrider as an example, but there are many more.
Also, MD puts a lot of weight on symbols, and symbols have a lot to do with perception, relative and individual thing, not that universal.
Which is great, because someone can bring something new and cool to a subject that was thought to be researched fully.
