Point taken. But there are some complex ideas that just need some amount of effort from the reader in order to "get" them. I don't know what is the right balance but if you are being introduced to new ideas, introduction of those ideas will also bring some vocabulary that you will (at least initially) be uncomfortable with. I guess I want to see someone communicate the ideas on less wrong in a simpler way without dumbing down or ignoring the nuances.
Well, if you have read most of his lesswrong articles(like I have), its hard to not enjoy the way he speaks and writes about these things. But I totally get that it feels obtuse and unnecessarily complex to someone without good exposure to his http://lesswrong.com/ writings.
I wish I could hear more about this. I haven't had such an experience and I am very curious about your observations. Maybe write about it?
I have seen many criticisms of lesswrong well taken by the community. For example:
