Even if a community exists for the content you seek, how do you determine the one that is going to grow? There could be a different version of that community on every server, which is the area I'm struggling to find content. Join every alternative is an option.
Unless there is something I'm missing. Quite possible as the federated approach is all new to me.
That was my thought as well, or assumption. I'm new here so it will take a bit to figure out the duplication model and what floats to the top, but I'm in for the adventure. =)
