In all of the threads I've read here about "Google hates me," and "Is it okay to post links to my forum in other people's forums?" I have not seen any discussion on structured data markup, microdata, AMP, or any of the other initiatives that Google, et al. seem to be advocating. I'm pretty sure none of this stuff is yet part of the core of any of the forum software (shouldn't it be?)—but have any of you gone in and added it? Do you know about this stuff? Do you care? Is your general approach "If Mike and Kier haven't written code for it, it can't be important!"
