Well this has been a discovery for me
I finished my work early today and started my afternoon working through a simple iOS 5 tutorial. As recreation, I went over to Hacker News and read a linked article by David Heinemeier Hansson on making the response time fast on Basecamp Next while still doing mostly server side processing. The article and the comments were great.
I need a few days to digest this, but this is likely going to change how I write Rails applications.
