I really like this idea. Mostly because I enjoy discussing things I read with others. Though I am having mixed feelings about the pacing.
It would take about 16 years to cover all articles on a weekly basis. Even with a daily pace, it will take about 3 years.
I would most certainly miss out on a couple of posts, but that does not mean I could not participate the day after.
Honestly, as someone new, I think it would be a good trade off. I heard about LW after HPMOR, and I know most people who recommended me HPMOR got intimidated by the amount of backlog they needed to do.
That is not a problem for me, but as I said in a different comment, I enjoy discussion about the things I am currently reading.
