Yes, I thought Ask City was particularly interesting, too!
Another thing I found nice about the article was, every "basics of optimization" article I've read says pretty much the same thing. I've applied every technique I have the know-how and/or time to maintain, but it's not enough to achieve a SE listing with anything close to visibility. (Last time I checked, I showed up somewhere around the twentieth page of search results, at best, in each of the four most popular search engines.) The techniques in this one, though, are mostly new to me. It inspires a bit of new hope in me.

My clients so far have come from other means, never a Web search, but I'm always hoping.
I'm not technical enough to judge whether they
really are useful techniques (or will be some day, as the article predicts), but I'm excited about the possibility. And since I'm preparing for some changes in my Web site anyway in the next two to three weeks, I figured what the heck--it's worth a shot.
