I am really enjoying your new article on Wd2; incisive, creative and compelling. You must have enjoyed researching it and writing it.
We are all beneficiaries of your "cluster obsession";
so thanks for the substantial effort that you put into your detailed articles.
Incidentally, I would like to note that the galaxymap website, which you link to in your article, is the brainchild of IIS member Kevin Jardine, a brilliant person (apparently not an astronomy PhD) who appears to have a professional-level knowledge about HII regions and Galactic Structure. His recent blog entries about the structure of the Milky Way Galaxy are amazingly detailed:

(I think that Jardine deserves a lot of recognition)
P.S.
(1) I shall comment on the scientific content of your Wd article when I have read it in more detail.
(2) I recently sent my Coalsack article to your yandex email.
