O’Reilly: Inside RIA

I've been involved in web development for about 12 years now and have always been involved in the early stages and client facing aspects of the development cycle. More often than not I turned to very low-fi methods of sketching the early versions of a UI such as paper, whiteboard or Powerpoint. None of these are ideal and the early agreed upon designs seem to get lost along the way. Also it's hard to make changes to non digital mockups. Recently I've been playing around with with Balsamiq Mockups which seems to be a great quick and dirty design tool for developers, designers and those who aren't tech savvy at all.
