Any chance of creating a feature to send out a status update at regular intervals saying basic stats ("John has learnt 53 new words this week!")? I'm not just in it for the bragging rights (in fact posting my stats at this point would be embarrassing), but I would think it could add a layer of accountability that some of us could feed off for motivation knowing that others will see how lazy we have been this week. Of course, this is something those so inclined could just post themselves at on a regular basis, but I think having a service that does it automatically decreases any tendency we might have to fudge numbers or skip a week. Might be hard to streamline with all the services out there, but having something available for one platform might be a start. What do others think?
