Allow an administrator to "connect" the site to social media by either linking the site using something like oauth authentication, or storing credentials.
Then create a "post type" that would auto publish to social media, like a news item, or announcement.
This would make things so much easier to cross post and allow this type of functionality to be transparent to users.
Currently you need to be logged into the company social media accounts in order to cross post, and it's a manual process for each social media site, not a one click effort. This causes an undue hardship.
I realize it's not for everyone, but having the option would help increase engagement rates for some, and it wouldn't "force" it on those who would prefer the manual method.
