A lot of people have said that they never look at Main, only Discussion. And indeed, LW's Google Analytics stats say that Main only gets one-third of the views that Discussion does.
Because of this, I thought that I'd point out that December has been an unusually lively month for Main, with several high-quality posts that you may be interested in reading out if you haven't already:
I tend to read http://lesswrong.com/r/all/new/
Much more handy to have one link to rule them all. Thanks.
You can use a good program like newsbeuter to fetch both main and discussion and also individual post as well.
