I have a Duolingo chart. I know lots of people do! It sure would be swell to somehow all be on the SAME duolingo goal... or to see how we are all doing, compare my progress to the community's, and then have a community with discussion around that goal together.

This would be awesome for any goal that has a shared measurable criteria... so, Draftin.com and other goals could all have a community, the ability to compare yourself to the community average, and so forth, while still holding on to one's individual criteria for success.
