So are you saying that having 3 links, which do not pass link juice, yet deduct outgoing link juice for the page because they are all to the same location, which according to most theories is the case, is GOOD practice? The theory goes something like if there are 10 links and 4 are the same 10% link juice goes to each of the seven links and 30% is lost. The second theory says that linking to the same location with two different anchor texts from the same page is even worse at confusing/prejudicing G as to the quality (link juice) of that link, whether you are trying to rank for the keyword or not. Or are you contradicting those theories because YOU consider them part of a header/footer, and can GUARANTEE that G sees them that way too? Are you somehow claiming that since G unquestionably recognizes them as nav links that their link juice drain will be "weighted" less? If G by chance doesn't recognize them as such, then they are no better than putting a dozen links to "widgets" all over the page. Perhaps G needs an alt=nav tag.
I agree the page is great for human consumption, but from all my recent experience I think you (as well as G) WAY overestimate G's algo abilities (in many areas)at this particular place in time.
