Sorry, I've posted it on every tDCS article I've seen on HN, and no one has noticed it. It took three posts in this thread to get anyone to see it. I'm trying to help people be more cautious about their brain cells.
People keep posting tDCS articles without any warning about potential negative effects. There are a lot of young, impressionable people here who might experiment with what is put in front of them. I'd rather have people see the information and get myself downvoted in the process than keep watching articles like this get promoted without any warnings attached to them.
