Why Yahoo Maps chose AJAX

Ted Patrick has posted a very frank and thoughtful post discussing the reasons why Yahoo has moved from Flex to AJAX for the latest version of Yahoo Maps. To summarize he identifies 3 main reasons for the shift :

• Shortage of Flex developers
• Problems integrating Flash advertising into Flex applications
• Complexity of migrating from Flex 1.5 to Flex 2.0

Despite these points it seems an odd decision in a year when so many great Flex applications have emerged.
