Yup. Ryan did a great job on the timeago lib. We have ever discussed about the pull request but finally find that we changed lots of the logic about how to deal with the relative timestamp. So we started a new one to give an optional choice.
Thanks for the feedback.
We are working hard to integrate the github(and some other services) with Pragmatic.ly. I believe you will like that. So please keep up with us and you will see the update in the near future.
We use the Ruby on Rails as the backend.
And use Spine.js for the front-end MVC framework.
For the the real time part, we use a service called Pusher.
Thank you for the feedback. We also love Asana. It works good but not quite well for us especially on software project management field. I agree the layout looks like Asana but we do a lot UX work instead of just riping off the Asana. Keep up with Pragmatic.ly to let us show you we're not a ripoff. :)
