This category and this category in the Japanese version of my blog contains topics on human languages, human communication using media, and human (and computer) networks and connections. The upper category is Blog from Kanada.
BTW, as shown on the top of the category page, the submission date of this page is intentionally set 0001-01-01 00:00:00. However, the actual submission date is 2009-01-18 13:12:04.
To keep the page light, I exclude photos in individual pages from the archive page. Instead, I inserted some of them here.
