Okaaay... personal feelings aside, do you have anything worthwhile to add to this discussion?
Yes I do.
Targted traffic doesn't change very much, even if you change your presentation. If the search engines deem your site worthy of targeted traffic then they won't alter their minds overnight because of a few navigational changes. If something is working well for you, stick with it; don't go on the other side of SE ethics because I said so. Link strategists best to keep link strategizing less fall prey to SERP oblivion.
