Joomla is a great application, CB is awesome, but what is amazing is the lack of a decent blogging component. Most community members want to blog!
Azrul's MyBlog is way over the top, the AJAX-powered frontend just turns the average non-techie user off immediately. Comprehensive yes, use-friendly it ain't - and this comes from someone who's already paid for it.
Mamblog is nice and simple, and is demonstrated well on this very site. However, it's clearly dead in the water, with the no development since 2005! The total lack of support means that no-one knows where to turn for installation/configuration issues (as evidenced by the lack of replies to any mamblog-related questions on this forum).
So, what are experienced community builders doing? Anybody out there with good coding skills want to put together a SimpleBlog product? Think simple a lá mamblog, but with a license fee...Go on, I'll be your first client!
