Thank you! I realize people have subscription fatigue, and that on this site in particular there's a culture of expecting to read the full text of everything for free. So I try to make the previews substantive enough for people to participate in discussion whether or not they sign up.

I do feel like the free sample guy at Costco, confident that once people try the cube of summer sausage on a toothpick, they'll want to buy the whole thing. But I sure appreciate someone else saying it!
