Well, I'm late to the party because of my sojourn in EU, but I am one who votes for Meditations. Yes, I love the content and helpful exposure of SoPW (learn something new every day!) and I'm becoming CB-addicted, but Meditations brings me a chance to read other peoples' thoughts on many subjects and also to spout a few of my own. I really need a few moments every day to divert myself, and Meditations does that admirably.
One other section that should have been included, however, which would have topped M, is
Saints in our Book. All hail the incredibly helpful guys & gals who make PM what it is!!!
