I think this is a part of the reason so many people focus on the comments over the article. I've found that whether there are a lot of comments and good healthy discussion is a excellent marker for article quality. The first paragraph(s) frequently are not. I agree with the 90% experience, but I have to say it is very hit and miss: let's say like 50% of posts that start badly are bad throughout. (And I do consider starting with an assumed context to be starting badly. It takes just a sentence to describe the fact _that there is context_ not present in the article if you don't want to include it outright)
