Last week, Twitter launched easy-to-install and lightweight "Tweet Button" that allows publishers to make it easy for users to share a link to their content on Twitter.
But what if you go to a site that doesn't have a Tweet Button? Have no fear. Twitter, now released "Tweet Button Bookmarklet" — just drag & drop the Bookmarklet into your browser's bookmark and you can tweet a link with your own commentary from anywhere on the web.
Like the Tweet Button, it shortens links using t.co automatically. If there's a Twitter account listed on the site, it also may suggest users to follow.
To install the Bookmarklet, visit this page and drag the "Share on Twitter" link to your bookmark bar on any browser.
