Need for Speed

Bosworth On Why AJAX Failed, Then Succeeded links to which isn't the first time he has examined AJAX's success and failures or why other technologies fail such as RDF. Some commentary was interesting in the comments and a few blogs, including this summary:

All in all the speaker (intentionally) kept his talk simple and stupid but here are some points I think are worth noting:

• Products fail because of [lack of] human psychology not poor engineering
• Top 3 keypoints of UI:
1. Speed
2. Speed
3. Speed
• Your app should be a tool, it shouldn't leave the user feeling like one
• Search isn't perfect but it is far better than any human can do so it is tolerable.
• Analyze the frequency of use of feature and implement those first
• If your app takes more than 2 seconds to load - forget about it
• The Motorola RAZR was cool enough so the poor UI (narrow keypad) didnt matter
