I have used both extensively.(it has been 2+y since I used Workflowy though)Dynalist just offers so much more, and  all the additional features are critically useful(at least to me).Does not seem to sacrifice simplicity in any significant way.But Workflowy is so much more popular, with an active community that builds stuff and creates resources.Besides the price and the first mover advantage, what is the appeal of Workflowy over Dynalist for you?It will soon be time for me to renew my dynalist membership, so I am trying to find out what I am missing.
