Thanks for posting this - I wrote about solitude/loneliness in the past (and published the essay here, too) - I will add this to my page (http://pa-mar.net/Lifestyle/Solitude.html) and also try to contact the author of the article.
Wow, this is a really thoughtfully written page. Thanks for sharing it Pamar. I'll want to take some time to really digest your writing and synthesis of others' perspectives on the topics.
