Pros
Pro Conceptually simple, yet complete
Most frameworks seem to tend towards conceptually simple, but also stripped down (such as Python's Flask), or go the other way and be very fully featured, yet complex. AIDA/web, however, manages to give a programmer a lot of expressive power, while remaining conceptually simple -- an afternoon will get you building websites, and you'll feel comfortable with AIDA/web in just a week or so.
Pro Smalltalk
Program your web app in Smalltalk, an enjoyable and easy language to use. Smalltalk was the language to inspire modern Object-Oriented programming and pioneered many of the programming concepts used today, such as MVC.
Pro Ruby framework based on Sinatra - with extra features
Padrino is as fast as Sinatra, but extra features are added to this framework. They include namespaced route aliases, nested routes, controllers, a mailer system, unified logging and a lot more.
Pro Open source
Padrino is open-source.
Cons
Con Relatively inactive
At the time of this writing, AIDA/web is 26 years old (first created in 1996). While maintaining pace with modern technologies (REST, Javascript, etc.), the community is small. You might find it difficult to find timely help, find resources and tutorials, etc.
