That's really interesting that they'd disclose their strategy so publicly. On the one hand, I can't see it doing much harm. On the other hand, wouldn't it be somewhat self-defeating or even embarrassing to confess that you're doing that? One could probably reasonably assume that many companies have a social media strategy like that, but to have people know that's the strategy would probably drain away at least some of the goodwill provided by the posts.
I would think it is good if done in a good way and bad if done in a bad way.
bad way - posting stuff to make your company profile go up all the time, if you think you have something that might be of interest to HN sure but not everything you do should get posted. when negative stuff comes up swoop in to defend company and to drag down those saying negative things about company, especially without disclosure but even with disclosure.
Good - something technical about company comes up, developers who worked on technical thing come in and clarify technical aspects for people. Somebody has problem with your product and you come in and ask for clarification and help solve problem.
It's a curious division between "old internet" and "new internet" (those on the *chans may have parallel but slightly different terminology for this dichotomy) to see people use BBS-style vs IRC-style emotive expressions.
