While browsing through the detailed reports from Sitemeter, I just made gratifying discovery: one of my posts is currently in the top 20 for a major Google search: The Nature of the Neocortex shows up on page 2 (Results 11 - 20 of about 807,000 for neocortex) of the results page for a search on "Neocortex".
I don't know much about how Google orders its search results, although I've heard that number of links and traffic have something to do with it. And, although I shouldn't say it, perhaps the fact that they advertise on this site has something to do with it. But Google advertizes on a lot of sites, and I'm guessing they get a lot more clicks from sites with less of a focus on nit-picking scientific details.
I don't know how long it will stay on the top 20: perhaps semi-forever, perhaps it will be lower tomorrow. But thanks to all the readers who created and/or followed links to that post.
