on-page link anchors post-Penguin Tag

Since Google rolled out its Penguin update in April of 2012, there has been divergent opinion on exact-match anchors in on-page SEO efforts. I've read articles by some SEO specialists suggesting that exact-match anchors in on-page SEO is bad. Certainly, it is widely accepted that exact-match anchors (the text that is the link) are a bad thing if overdone in backlinks from external domains. In Google's view, it's not natural. A website would have diverse backlink anchor text. What about on-page anchors?
