This "ephemera" subsite continues to be completely invisible to the search engines -- the usual fixes (sitemaps, manual robots.txt, etc.) seem ineffectual. No indexed pages in Google, all sitemaps inaccessible to the search engines. Perhaps due to the present focus of the search engines -- blog content generated by hand used to be the gold standard for search, but it wouldn't be much use for the uses that search engines are put to these days.
I don't think I've ever had a computer that worked exactly as it was supposed to all the time. We blunder onward through the forest, bread cast on the water, breadcrumbs cast on the darkening path.
