Comment on WordPress SEO Plugins by Mark.

WordPress SEO Plugins About WordPress plugins I would second what Dave said above.
My plugin philosphy –
Before I used Dave’s themes I had scores of plugins to try to SEO my blogs.
Now I just let the theme do the work (with a few plugins like related posts and sitemap).

I found my pages load faster and less conflicts, with a good theme. When you load up with every plugin under the sun there is a lot of extra code on your pages and potential for conflict or wrong SEO moves like mentioned above with nofollow. That is why it is better to use a well coded theme. Talian works very well.
