After luring away several Interwoven staffers earlier this year, open source ECM vendor Alfresco has beta-released a long-awaited Web CMS module. I haven't seen it yet, but it will be interesting to see how a platform that is long on repository-oriented services will deal with the particularities of web publishing in general, and customer expectations for web site management in particular. If you end up using Alfresco for web content management, I'd love to hear how it turns out.
