I agree with JayMatt. How many people will read such a sefer and come out with piskei halacha which they otherwise might not know? Sure, you could argue that they could have and should have gone through the halachos themselves, or asked their rav, but realistically, not everyone does. JayMatt certainly should be commended for spreading it to an audience which can gain from it.
And with apologies to all, I must say that a light sefer with easily readable piskei halacha is at least as kosher for “entertainment” as what anyone reading (or writing) this does for leisure.
