Great idea! I've been following Haejin for the last 2 weeks now and am amazed by his skill and love the way he explains his charts. I'm not yet in a position to contribute, as I'm learning, but I'll definitely be following this and hopefully contribute in time!
Thanks, hopefully this becomes a place where people learn they can go to to ask TA questions and receive feedback. Right now, someone might post a chart in one of @Haejin's blogs, but he is so prolific that many of his followers move on to the next one and miss the chart.
