I have one of the longer continuous poetry and poetics blogs (since September of 2002). They seem to start up or fade away in clusters, or in some cases migrate from one url to another. I certainly understand the impulse to quit: blogging gets in the way of other ways of wasting time. For me, though, it has archival value that other ways of wasting time do not. Imagine if you had a record of every interesting thing you said to your friends in the coffee shop?
