Aside from the usual under-the-hood improvements, Safari 5 ships with a new feature called Safari Reader. The concept is simple enough: you're reading text on a Web site but don't want to be distracted by terrible page layouts and extraordinarily annoying animated advertisements. You activate Reader, then the browser isolates the text and applies a far more readable formatting to the text. The result is much cleaner text, and text that doesn't destroy your eyes trying to read. The best part is that you don't need the new Safari to replicate the same functionality. I speak, of course, about Readablity.
