Beyond Twitter: Enhancing your thinking in real-time via "Brain Buddies".
https://news.ycombinator.com/item?id=508924The idea here is that you would be paired up with a "brain buddy" who is currently online and wants to increase his/her thinking ability just as you do.
As with Twitter, you would tweet your thoughts in real-time to your brain buddy and he/she will tweet his/her thoughts to you. Unlike a chat, you don't necessarily expect a response for every tweet.
You can try to help each other at any point. If your brain buddy has been helpful, you can give him/her points. Doing so increases the chances that you will be paired up again, especially if you both give each other points.
