MT 4 has failed several tests. This is why I moved off the platform and onto WordPress in the first place.
1. SLOW SLOW SLOW when you have thousands of posts like I do. The template republishing is the same reason why I moved from Radio Userland.
2. The Dynamic publishing is too difficult for a non-PERL person like me. I had hoped for this to solve my MT problems last year, but no go. The switch to Dynamic publishing just didn’t work, and there were no helps out there that I could find.
3. I just tied to login using Windows Live Writer, and boom….error. Again, MT still can’t do it for me. I still want to get my posts into Community Server. The BlogML imports have yet to work. Some malformation of my WordPress Export, but I have yet to find a validator out there. So, it’s still WordPress for now.
