I wouldn't cross-post everything, I don't think, just the particularly relevant or good bits.
I've taken about a philosophy minor's worth of classes in ethics and read most of the really influential modern work in the field. I may end up in grad school studying metaethics in a couple years, though that's far from certain.
I've resumed blogging For Real This Time™, starting with an introductory overview of the distinction between metaethics and normative ethics.
Should I cross-post it to LessWrong? Should I link or cross-post future blogging about metaethics and other LW-relevant topics? Is it rubbish? Inquiring minds (mostly mine) need to know!
