I moved my personal site from Wordpress to Octopress a few years ago, which is a small site - approx 70 posts - and gets a small amount of traffic.

Pros:

* Cheaper / simpler hosting - no need for a database, etc. (you can even host on GitHub)

* No updates to install on the server, as you're serving static files

* Less concerns over security

Cons:

* Not as simple to add a new post. With WordPress you can just login, create a new post, and publish. With Octopress you run a rake command, edit post, save, preview, git commit, then git push / rsync.
