I'll be doing it again next year, my 3rd year for it.
I don't scrap every photo though. Last year I just did a blurb photo book with it and that was nice & low pressure. This year I am doing multi photo pages, not grouped by week but by however it seems best for me, mixed in with layouts I did scrap of 365 photos.
From experience, I suggest having an overall theme or certain things you photograph every month. It helps me keep going.
