Has anyone stuck with Swarm or Happenstance after the first look?

has anyone here put real time into the swarm or happenstance? i'd like to hear from actual users rather than the landing pages. 1. which of the two did you stick with, and why? 2. is it still in use a couple of months later, or did usage drop off after the first look? 3. how did you persuade investors and others in your network to connect their contacts? the graph is only as good as who joins, so any lessons on that ask would help a lot
