It is said that Rails is opinionated software. I’ve been exploring to see how it stacks up on a subject area where I have opinions: weblogging software. So far, it has measured up pretty well.
I'm reminded while reading the article, why I don't like Ajax, and for that matter Flash.
URIs are definitely something I have an opinion on. I don’t cotton to the idea of putting the action in the URI as I feel that URIs are intended to uniformly identify, well, resources.
With Ajax and Flash the URI is taken away, and we lose a means to identify some of the resources provided by the Ajax and Flash app. Not everything falls under this though, for instance a flash movie, or the Ajax based Gmail interface.
