I recently started using the Hevy app for logging my workouts, and I really like their social features. Every workout is almost like an instagram post, and you can follow other users and like their workouts and comment on them.
I just had the thought that it would be pretty sweet if I could do the same thing here, but with my diet. Being able to "publish" my diary with some commentary text and a picture/video would really increase the social interaction and community aspect of Cronometer.
So I'm just gonna leave that idea here, in case you want to expand the site/app in the future.
