Looks good.

In that template the code for your left sidebar is above the code for your center column, meaning the spiders will read all of that and maybe stop before getting to the content in your main column (if your page/sidebar is a long one).

That's why I mentioned looking for templates that say they're SE optimized so you can see how they put the main content first and use CSS positioning to make it appear where they want on the page.

(which is how 'on-the-fly' can be done too)
