First of all why bother quoting any of it? You will note that I link to a lot of articles. Generally I don't quote anything, and it doesn't seem to be a problem. People know what the article is about before they go there, they know that I like it, and the article can stand on its own. If it can't do justice to itself, then I shouldn't be linking it anyways..
The only time that I will quote is if there is something important buried in the article that I think that people will miss. Then I quote, not to encourage people to read it, but to ensure that they notice what I did.
As for conversation being stifled, what happens is that your post is so long that it is hard to indicate which parts of it you did or did not want to reply to. Besides which if a conversation did start, it is such a pain to enter into the top and get to the discussion that people don't bother.
As a demonstration note that the real entry point for this discussion is not your post. It is my much more managable brief response. You posted, I replied, and discussion got going below that.
I mention this because you do find a lot of interesting things, but don't get as much discussion about them as I think you deserve. Take it not as an insult, but as a tip on how to more effectively spark discussion going forward.
Cheers,
Ben
