Your second point is especially good. Consider also how many persoal blogs go fallow within six months. For companies, there were fewer than 30 of the Fortune 500 with any sort of blog, so divvying them up into honest/direct vs. corporate-speak blogs at this point might not be so informative. But yeah, the challenge is to get CEOs talking like real human beings when blogging. If they can’t, it’s better not to try to force it.
