I’ve recently become interested in something called Habari. It’s got a slicker admin interface than WordPress, but lacks a TinyMCE plugin. However, I found one here:

So why Habari over WordPress? Well, unfortunately you would be correct that there’s just so much community momentum behind WP, and more so behind that than Habari. However, what’s neat about Habari is that it uses PDO, PHP5 features, and has a style among the files that any WP developer would feel right at home with. And, unlike WP which is MySQL-centric, Habari is cross-platform for SQLite, PostgreSQL, and MySQL.
As well, just like WP, Habari can be converted from just a blog engine into a CMS for a variety of situations.
And unlike TextPattern with its klunky language for the page text in the admin system, Habari uses HTML, which I like better. And with the TinyMCE plugin, it makes the HTML editing far easier for when I pass this off to a client.
