Instapaper is a very handy site to have at hand, especially if you’ve got an iPhone (as you can see from above, it’s a very lightweight design). Basically, you create an account, install a droplet in your browsers and as you come across interesting sites you use the droplet to add a link to the site to your account. You then have instant access to a “newspaper” of articles you already want to read whenever you find yourself with time on your hands (such as on public transit with your iPhone). I’ve also found it extremely useful when you find an article or a site at work, you can effortlessly save it for when you get home. (Via Gruber)
