Wordpress:

* Simple to set up

* Can write in HTML or use WYSIWYTYG editor. Can post from external clients that support Atom Publishing Protocol or Wordpress's XML-RPC. Can easily post from anywhere.

* Disqus plugin incorporates comment text into the actual page without javascript, so Google can index comments at my site

* Plugins provide relatively painless media embedding

* No good source embedding, but gist.github's secret .pibb format (http://gist.github.com/15914.pibb) provides a stop-gap solution, and I'm sure I could get someone to write a plugin to automate that.

* It's written in PHP and MySQL, and I hate PHP and MySQL.

* Since of course I will immediately become famous and widely read, Wordpress's dynamic page generation could be a performance issue.

Webby:

* More complex to set up -- I have to write posts, run the generator on them, and then upload them to the site. This can be automated, but it's still a higher level of effort.

* Can write in HTML, Markdown, whatever. Can write in my favorite editor easily. However, if there's infrastructure for the blog on my personal machine, I can't easily post from other machines.

* Disqus integration would happen via javascript; Google would index comments at the disqus page.

* Media embedding is more difficult, though a few custom template tags can make this easier.

* Excellent and very customizable source embedding.

* Not written in PHP and MySQL.

* Static files scale very well.

On the whole, I'm leaning towards using Wordpress, due to a lower amount of up-front effort needed, but I thought I'd get your comments, if you have any to offer.
