A productivity app for developers called "Taco" just finished a successful round of funding on Kickstarter and it looks like it will be available in September. First, let's look at why the creator of Ruby on Rails, David Heinemeier Hansson likes it:
Nice kickstarter for a unified todolist that brings content together from Basecamp, Github, Google, and others: http://t.co/To88EwsXh6— DHH (@dhh) June 19, 2013
DHH is a creator of Basecamp, so he certainly has a reason to like it. Taco aggregates Basecamp todos, GitHub Issues, Google Tasks, Trello tasks, Asana tasks, Zendesk tickets, and any RSS-friendly services.
