“Since getting Instapaper Pro for my iPod, I’ve been loving the ability to add links to my instapaper just by tapping on them, rather than (on my laptop) having to follow a link to its webpage, wait for it to load, and then hit the bookmarklet to send it to IP. So I made a service to duplicate that functionality on my Macbook. Once installed, you can select any URL in any application, and any link in Safari and send it to Instapaper in the background. You’ll get notified via Growl or the OS.”
This is just great.
