For a new user, the majority of resources seem to be focused around helping them find a pod that accepts new users, and one that has services you want, and maybe one that is more geographically close to you.
Unfortunately a significant part of the choice is a question of privacy and trust in the podmin, and this often goes unmentioned. On the pod uptime site, for example, only 11 pods have any sort of podmin statement. Many pods have no information at all about who operates them. For a private pod this is entirely understandable, but it should be unreasonable to expect any new user to sign up with a pod with an unknown operator.
So, partly as a personal question, and partly as a concern for the expansion of the diaspora network / the Federation, how does a user find a trustworthy pod?
