I've been wondering this... and let me be clear: by link variery, I mean the TYPE of links (article, wiki, bookmarks, forums, etc, etc, etc). I haven't really been using a ton of variety since Penguin made quality so important, yet I haven't really seen much bad happen. I've been fairly successful, even. I find it odd... that engines are so obsessed with quality. I used to pump everything, but not just two types of links really. What have the rest of you experienced? Have you too noticed this? Has G tightened things SOOOO much that they only care about absolute HQ links and not variety anymore???
