This is my defense of necroposting:
I view Brown Café like a recipe box. I may not go to certain posts all the time, but it's nice to know that certain subjects are already there and I add to them as time and opportunity presents.
It's like if I get a new recipe for a cake......there's already a 'tab' marked "cakes" in my recipe box and that's where I would file it, not make a new tab. See?
