Part of my interest in this turn to Twitter comes from disappointment with most university press blogs, which often seem more like PR vehicles than genuine blogs with discussion, disagreement, expressions of real enthusiasm or curiosity or whatever. Reading very many of them at one sitting feels like attending a banquet where you are served salt-free soda crackers and caffeine-free Mountain Dew that's gone flat.By contrast, university-press publicists seem more inclined to experiment and to follow tangents with Twitter than they do on their own official websites. They link to material they have posted at the press’s blog, of course – but also to news and commentary that may be only obliquely related to the books in their catalog. It’s as if they escape from beneath the institutional superego long enough to get into the spirit of blogging, proper.
