I recently launched my new project - https://app.getlearningstory.com.
The main idea is to encourage people to journal their daily learnings and share them with others. Learning Story has a simple design similar to most social media. You can post about your learning activity, and people can discuss your post.
I've also added a few features to encourage people to do this daily:
Score system that we calculate from your activity
Leaderboard of people with top scores
Ability to add the goals and complete them
I hope this community will grow over time, and we gather passionate learners together!
Right now, the website is free for everyone who willing to try!
