So where does that leave us? I am struck by a comment Jon Udell once made – context is a service that we provide to others. Perhaps that is the form our libraries take on the web. Not of 10th century manuscripts but of contexts of thought. So a blog I consistently read is from an individual’s unique context – how she is, what she is thinking, what she is reading, and who she is interacting with. That context then sits aside other contexts. Soon enough I have amassed a library of context. And when I blog, the many contexts of others I have been reflecting on shows through in the context I share.
