Here's an example of one (healthcare) community that try them: https://q.health.org.uk/community/rcts/
> How does it work?
> Every member who signs up will be sent the name of another randomly-chosen member on the 1st of every month. Each pair can arrange a brief informal meet-up at a time that suits both parties – be it a phone call, Skype call, Google Hangout or even a coffee in person.
> “RCTs have given me the opportunity to talk to people who work in areas that I don’t usually come across in my day to day work.” Lesley Goodburn, Patient Experience Consultant
> RCTs allow Q members to connect with a new member each month and hear about what other colleagues are working on and share any ideas and inspiration. There are no rules here – RCTs should be viewed as an informal opportunity to connect with peers, however if scheduling means that you can’t meet that month then it’s ok.
> We think you’ll enjoy these fun and fruitful conversations – it’s organised serendipity. Matthew Mezey, Q’s Community Manager has written a blog about the benefits of RCTs.
