No, in fact I don't. But this post wouldn't be of any help anyway. It feels like it's about nothing, there is no substance, just stating some obvious facts. Without examples that lead to some real recommendations, this whole expertise claimed by the author is of no use.
That's harsh. I believe the author really does get questions from people who want to register a well known path, and probably some of them really failed to consider sites with ~user paths or whathaveyou and this post might push them to use a better solution.
And if you read that and still feel confident that you want a well known url, he links you to the registration process.
