I've just seen that someone on my friends list got 5½%.
I really don't think that this person cheated either.
By comparison, you have nothing to worry about.
I'd have linked to it, but it's friends-only.
If you're reading this and you are the person who got 5½%, well ... what can I say?
We're not worthy, we're not worthy ...
EDIT: I seem, once again, to have been guilty of leaving things unsaid, of trusting people to read between the lines.
The person concerned, by contrast, is worthy: worthy of my best regard, not because he's an "exceptional data point", but because despite (because of?) this, he's well adjusted, knowledgable, and able to turn his wide experience into support and gentle non-judgmental advice to people who are confused and hurting when they're in unfamiliar situations; worthy of my best regard because I've drawn on that support, that gentle advice, from his writing when I was in just such a situation in the late eighties; worthy of my best regard because he's amongst the three or four most honest, most complete, people on my friends list.
yonmei said "Must be an educational kind of friendship.". She was right, and in a good way at that.
