This is post #100 on the Expat Almanac. It’s a milestone, of course, but one without any real significance. It does serve, however, our psychological needs. Why do we post? For the same two reasons, I suppose, that people post on Facebook or tweet on Twitter: the need to belong and the need for self-presentation. (The link points to a Boston University study that found those two primary reasons for participation in social media.)
