Mac OS X Server will include a weblog server. The following can be found on Apple's OS X Server page:

Weblog Server Now non-technical users in your organization can publish web content without any special software. Calendar-based navigation and customizable themes make it easy for users and groups to publish journals, share project information and post entries right from their existing web browser. And since Weblog Server is based on XML, they can syndicate content using RSS in Safari or using weblog clients that support XML-RPC or the ATOM API.

I must have missed this feature in all the talk about the release of Tiger, the next version of desktop Mac OS X. I can't find any other mention of this feature on the Apple OS X server pages. The only reference is the paragraph I copied above.

I first read about this feature in a Wired article about the release of Tiger tomorrow.
