Actually he's posted a big notice saying Gone Fishin' on his home page with the message 'Back soon...' It's a message you instinctively distrust, especially with those ominous three dots.
As I have pointed out before, blogs are delicate things which need nurturing – more accurately bloggers are (usually) anonymous people who need nurturing and do blogs because they enjoy doing them. But they could do with a bit of encouragement now and then. So all together now, email our Norm with the simple message 'Keep it up.' And maybe he'll be back sooner than he expects.
