I know this is disappointing, but I'm glad they open sourced the packages (see: <a href="https://github.com/quantopian" rel="nofollow">https://github.com/quantopian</a>) I could see it having been worse, e.g., where the entire ecosystem disappeared.<p>Perhaps there is an opportunity for another player to mix and match the open source packages into an alternative community. However, if Quantopian is shutting this down, it is probably because the economics doesnt make sense (perhaps accounts dont convert well?)<p>Anyone know what happened?<p>Edit: Lectures seem to be gone too!
