Here's where the situation stands. My friend hasn't thought to take my comment off by himself.
my limited profile is still there.
So I know for certain he hasn't been on my blog. He lives in Japan, I'd have noticed it on my Sitemeter. The only thing I may have gotten is a visit from a friend in common who also comments on his blog. Since he posted his blog on Facebook, I had a window of about an hour and a half where any of his friends could have seen it, so Canadians. I'm not sure if I really care. They're not close enough to mean anything really.
But the situation is still at a stand still. I think I will ask him to remove it, offhandedly. I'll mention it to him. I just have to figure out the right wording.
At least this way I can post my blog back on my profile.
