I was wondering about that as well. Sounds nice for an investor, but then - investors want to take profit, so that means generating selling pressure.. albeit, quite predictable selling pressure. It would be nice to hear about that from time to time, just to keep an eye on the stats, experiment is live, is there someone researching the effects? I have no idea. Quick 15-second search found two posts, distant in time from each other. I've yet to read them, but maybe you'd like to take alook as well. At least the first paragraphs of the first one sound reasonable, and the title of the second exactly states my doubts
