A lot of organizations optimize their websites for mobile. Unfortunately, that doesn't mean these sites aren't cluttered with ads, extraneous links, and all manner of other junk. Reader, a built-in iOS feature in Safari, strips a page down to its bare essentials. While it's not a dedicated feature of the operating system, you can achieve the same thing on Android using a Readability or Instapaper bookmarklet.
On Chrome in Android, go to Readability's bookmarklet page here and press and hold the "Read Now" bookmarklet link at the top of the list. (If you prefer Instapaper, go here and do the same thing for the Text bookmarklet option). In the new menu that pops up, tap "Copy Link Address." Create a bookmark to this page by tapping the star icon in the upper right corner of Chrome. Give it a name that's easy to type, paste in the Javascript address you copied before, and save the bookmark.
Now, when you visit a website in Chrome, tap in the Address Bar and start typing your bookmark name. Gigaom's Kevin C. Tofel recommends starting the name of your bookmark with an asterisk so that it pops up immediately when you start typing. Now, the page should be stripped of all those extraneous menu bars and advertisements, so you can read in peace.
