Setting up the service, which requires no signup, is extremely simple—just enter in your twitter account information on the Twitlet site, then drag the bookmarklet up to your toolbar. Clicking the bookmarklet will display a small JavaScript prompt where you can type your new status message—and you can use the special #link or #this keywords to add links to the current page using URL-shortening service is.gd. Security-conscious readers will note that your account details are encrypted and stored in the bookmarklet, and as with any third-party service you may be concerned about giving them your account information. The ease of use factor alone, however, makes this worth a look.
Twitlet is a free service, works with any browser that supports JavaScript bookmarklets. If keeping Twitter updated is killing your workflow, you should check out our guide to getting productive with social media.
