I'd love to see todoist as an option for AddThis.
Are you referring to a plugin or service? Please try to link to it so people know. Also, feel free to add this to our Votebox area. http://todoist.com/Vote/
This would be a great addition. I can add links to Todoist on my phone using the share function (there is an option for adding as a task or a note). Would be great to do that on the computer as well (and doing it through AddThis would be great). http://www.addthis.com/
