I haven't checked recently bhartzer's reports of his anchor text experiments (Supporters area) that suggested that anchor text links were not working as well as before. But these recent changes seem to vindicate his research.
Although I read this I haven't been following.
I've used the "broad, exact, phrase" match in link development since 2008.
I take all holly grail phrases and cut them into single-word phrases and develop links on these... so if search engine optimization was the holly grail phrase I get links for >search< >engine< >optimization<
As with AdWords this allows me to find swaths of longtail phrases that were never considered before... and if not #1 a link or 2 is developed... that diversity allows finding more swaths that are similar to Adword phrase match for partial matches on (using the words I exampled previously) >search engine< >engine optimization< >search optimization< >engine search< >optimization search<
...which avoids bhartzer findings/issues because no single phrase is overwhelming targeted (thus no unnatural anchors).
