“Dare Obesanjo recently enumerated some key points that Ajax application architects have to contend with and a few of them are particularly worthy of note including how to deal with the need for permalinks, the Back button, and others. Please check it out. He also notes that MSN will be talking about their best practice Ajax techniques at Microsoft’s PDC developer’s conference next month, which it looks like I will attend. Since a prerelease version of Atlas will be available there as well, expect some updates here on this blog on the latest.”
