... it occurred to me today I'm wasting far more time than I used to waste on email and forums (before I did some time analysis and cut down) ploughing through endless 'low signal to noise ratio' blogs for little real positive result.
That's good Ian. The 1st step to recovery is to admit you have a problem. No, seriously, it's definitely a time killer. I found myself dropping newsgroups for blogs. Different sort of information organization, but you sort of adapt. I'm pretty good at marking a month's worth of blogs as read without even glancing at it.
