iDoneThis is a great web app to keep track of your daily tasks.
I was wondering if there is a way to view your iDoneThis calendar in Google Calendar?
Under your iDoneThis calendar are three links: Share, Feed, and Invite. Click on Feed and turn on the secret link. You will be given a link, and this is what you feed into Google Calendar. Now just follow http://www.google.com/support/calendar/bin/answer.py?answer=37100 to feed your iDoneThis into them.
