Stateless apps don't expose any information about what has happened or changed since it started running

Stateless apps don't expose any information about what has happened or changed since it started running. They give the same response to the same request, function or method call, every time. HTTP is stateless in its raw form - if you do a GET to a particular URL, you get (theoretically) the same response every time. The exception of course is when we start adding statefulness on top, e.g. with ASP.NET web apps :) But if you think of a static website with only HTML files and images, you'll know what I mean.

What are the benefits of a stateless web application?

It seems some web architects aim to have a stateless web application. Does that mean basically not storing user sessions? Or is there more to it? If it is just the user session storing, what is the benefit of not doing that?
