Actually, its more because most persons who'd have something intelligent to say on the tech side, mire the conversation in too much jargon and have a hard time following general writing principals.

Those who are able to make the transition end up becoming more journalist than technologist and therefore lose a bit of that edge in technical knowledge, because the demands as a writer are just as much as if they were coding/developing/prototyping/managing.

I say this from direct personal experience. Its just very hard sitting in both worlds and doing them equally well, unless you have a team/org/company behind you that allows you the freedom to, and the push from, to grow in both areas.

When media companies change to adjusting to the pace of technologist writings, then you'll notice a difference for the better in terms of the quality of pieces. Hopefully, those companies which have writers also working as technologists would be able to hold onto and culture those writers, so that items like the Post and Times can actually have something intelligent to say.

I'll tack on, mobile as a field is very wide and deep. There are very few people, let alone orgs, that have a wide-enough view to always report things well. Not counting this article of course, as there are items that could have been stated better if simple research was done. But mobile is big, and there's a lot happening with it that's well and beyond most person's personal and professional scopes.
