Chrome: Albeit a little late, Evernote has jumped on the improved website readability bandwagon and introduced a new feature called Clearly. Much like most browser extensions and bookmarklets, it takes a given website and converts the layout into a more readable format. This makes clipping web content to Evernote a lot nicer as you won't have to deal with improper formatting as the page transitions to your notebook.
Evernote is clearly (no pun intended) adding a feature that has existed on the web forever. Readability, Instapaper and ReadItLater are all popular and long-established options. Chances are you already use one of them, so you're likely asking the question why you'd bother switching to Clearly instead. Since it provides much of the same functionality, the main draw is that you can save pages for later in Evernote. One of Evernote's main features is clipping web content to your notebooks. Clearly is just a natural extension, and should be very welcome if you rely on Evernote to save content from the web.
Currently Evernote Clearly is available as a browser extension for Chrome only, but wider support is underway. You can download it right now, for free, in the Chrome Extension Library.
