You're right...my comments are quite severe, and probably over the top. So I apologise if I've offended.
But I do think that in an article the presentation is as important as the content, in the sense that the content will never be considered by a large section of the readership, when it is poorly presented.
I also know from experience that writing articles is hard work and takes time. It is however a very rewarding experience, and I'd encourage others to try their hand. However to maximise their chances of their articles being well received, I'd recommend spending a certain time on the "packaging", which can show their technical contributions in the best light.
(But I do think the editor should be a little more proactive in this regard.)
A final point, it is clear that the author has good English, grammar and spelling, and can put together a sentence or paragraph, apparently without too much trouble. I just wish he'd done a couple more, to put his script in context.
