Good for you! You asked how original sin and fairness fit into my view, but your enthusiasm for GAE took over the rest of your comments. I’d like to answer on both counts, but I’ll start a new topic to separate the two, since one has nothing to do with the other.
I’ll restrict my GAE-specific replies to this topic, and the other will be a GAE-free zone. Deal? I’ll come back and post the link after I write the OP. I’ll post a reply to your GAE questions later, maybe tomorrow.
