Readability 2 makes webpages printable, pasteable and uncluttered
If you need to copy-paste an entire article without grabbing images or accidentally copying weird formatting tags, Readability 2 is just the ticket. Code and pre tags are also preserved, so Readability 2 won't destroy the formatting of code snippets on a webpage. Mr. Terpstra points out that it's also great for getting text ready to be grabbed with capture tools like Evernote.
