This is one of the best discussions I’ve seen about the practical advantages and disadvantages of using AJAX versus Flash for RIA’s (rich internet apps). It points out how using AJAX and Ruby on Rails can speed up development time when compared to building those same RIA’s in Flash. I think its interesting that this discussion is happening on JD’s blog over at Macromedia/Adobe.
