Is there a comparison of the SEO capabilities of different blogging software/blogging plugins?  I'd like things to be as optimised as possible.I have a basic grasp of SEO principles, probably 12-24 months old.I'm about to start a blog, after having a few previously.Also, I'm not up to speed on what pings are in the blogging world.  What are they, and how do they work?I assume it is best to have blogging software that automatically pings.
Search engine friendly, SEO blog software

I did a quick Google search and didn't see any comparisons of blogging software for SE friendliness. But Wordpress is definitely built to be search engine friendly and can be made even more so using a wide variety of plugins.If you want to  know more about Pinging read these two questions:What do Trackbacks and Pingbacks do?Does pinging the page on social bookmarking sites whre your site has been bookmarked help SEO?
