Google Reader added a way to share posts in a number of other services, such as Facebook and Twitter. In addition, they offer a way to build your own custom links right into Google Reader. Upon seeing this, I immediately thought of making an Instapaper link so I can read posts later on my iPhone.
Here is how I did it:
- In Google Reader, go to Settings and click to the Send To tab
- Hit “Create Custom Link”
- Enter a name, I used “Instapaper”
- For the URL enter this, but replace YOURUSERNAME with your username:
- https://www.instapaper.com/api/add?username=YOURUSERNAME&url=${url}&title=${title}
- If you have a password, put this instead (Replace with your password):
- https://www.instapaper.com/api/add?username=YOURUSERNAME&password=YOURPASSWORD&url=${url}&title=${title}
- You don’t have to use an image, but if you would like to, feel free to use mine:

There are many other services that this could work for too.
