Do you use an anonymous social workplace app like Blind or Fishbowl?

I ask this question because it feels like prediction markets would be a powerful thing to bolt on to these apps. I'm curious about the crossover between prediction market folks and those other apps.

I think it'd make for a powerful engagement mechanism if a Blind user could start a semi-private prediction market that is only visible to those in their workplaces community.

Or Manifold could bolt on these social features, and Manifold users could verify their employment and start markets only visible to coworkers.
