I have been playing around with this a bit in the past few days. I was a bit surprised by the way it worked... And thought it was just sharing the same post in a different community (which would address the problem that I have of wanting to belong to a few communities...), I didn't expect it to create a new post!
As it is, it isn't what I hoped for... But I hope that there will be a way to be able to post across communities (it doesn't appear that having multiple jobs tags works?)!
Nah, this is much more geared towards sharing other people's content.
I also think there is some confusion as many seem to not distinguish the difference between an interface and a community at the moment. That'll change though.
I am hoping there is a way to post to multiple communities using the same instance of a post coming, kind of like the resteem works to add it to the blog roll, where the "resteem to community" function exists. Not my area though :)
