As far as I'm concerned this is just another piece of opinion put online by a programmer. That's not a bad thing - putting things out there and talking about them is integral to the programming profession as a whole. Look at the body of writing work out there written by programmers that's considered 'classic' already. Never mind that most of the discussion is usually subjective, highly opinionated, often misinformed…
I like threads and tree like comments as it can be interesting to see the ideas and feedback at play. But sometimes I think it would be far better if the comments remained completely on topic.
The problem is good jeurnalism is inherently difficult. I resist writing blog posts because I'd spend too long on a post. As a teacher I'd spend a day at least on a hand out. And a post requires listening to feedback and fine tuning it. That's great if you have an informed receptive audience.
If I do ever bother with a blog, I think I'd ask for my desired feedback. I'd like users to submit links to relavant associated content.
I do enjoy a 'good' article about programming, I specifically like to hear about people's mistakes.
