I'm sure you know what your talking about, but pushing the point that what is "best" or worth talking about is something that changes like every month does not really help defend against the case that most of this is just hype-churn or marketing.
I'm not pushing what to talk about so much as pushing the point not to talk about stuff that is obsolete and starting to smell.
It's that hype-churn marketing that is a motivating factor for the groups to innovate, much like Formula 1. It might be distasteful, but that doesn't mean it isn't working.
