Shortly after I came here I had a look at my feed, because that's what I always do, and someone had published a post about a community, then minutes later cross posted that post into the actual community they were writing about.

There are quite a few well-intentioned folk who didn't realize what was going to happen when they cross-posted, they thought it was just going to appear in the community, not create a new post. Learning curve issues.

There are things I can add in the 'pro' department, and quite a few for the 'con' section.

Definitely. However, this is the first iteration and given the chance to evolve, it might be great. Or not, but we have suffered worse perhaps :)
