With cross posting feature you can post one single post into more than one Communities
Because of this you don't have to post same content again, any one can click on the link and get the see the original full post
Please anyone correct me if I am wrong
One should be able to select from a list of communities before publishing. Write your post, add your images, tag it, select which communities you'd prefer the post exist within, then hit post. Simple.
I think we can not post in more than one Communities at a time currently
I had a strong feeling people wouldn't want to sacrifice potential eyes on their work for the sake of being organized, so of course they'll want to be in more than one place at a time. That's why Tribes were a hit. One post in multiple places means more potential viewers. Selecting categories or communities before hitting 'post' would be the way to go. So much simpler and Tribes already proved it worked.
I agreed with you
Yes, but it will get rewarded twice. For those who constantly crosspost their own content, I am more likely to flag all of them.
Good point it's not come in my mind
Its means cross posting feature have no value or use case
