Chrome: We love a good quote here at Lifehacker. Using the Pullquote app for Chrome, sharing quotes on Twitter is easier -- and prettier -- than ever. It makes the quote a nice, retweet-friendly image.
Once you've installed the app and set it all up, just browse as you would usually. When you find a quote you like, highlight it and you'll see a menu with some options pop up. Simply select Tweet, make whatever modifications you like, and post. You can even save your favourite quotes with tags for easy access later.
Pullquote also makes it easy to tweet an image. When you find an image you like, click the Quote It button in the corner of the image, crop as needed, and tweet it. You can use Pullquote as a simple bookmarklet or download the app at the link below.
