If it seems that there are more hit-and-run posts than usual this summer, and fewer longer expositions, it’s because there are. I’m deep in another medium — a book that needs to be finished by the end of August — and in many ways it’s refreshing to be back in the old mode, where revision and second-thoughts take place before publication. But you know what I really, really miss? Hyperlinks. Writing without the allusive immediacy that links give seems somehow artificial now. So thoroughly have I internalized the newer ways of communicating.
