Workable procedures will develop in time. I think any twitter posts showing facts such as data and pictures should also be reproduced on the company's website.
Personally I've banned all social media apps from my company's computers, except one firewalled desktop where we monitor some product technical updates on twitter, but not to be used for social media in the personal sense. Twitter's strength is speed. For example, alerting interested communities (e.g. users of a particular piece of equipment) of critical changes to maintenance procedures etc. The alert can then be followed up in detail via more conventional channels.
When people re-post twitter links on HotCopper I just see the message: "Cannot load tweet. Disable your adblocker and tracking protection."
I've never subscribed to Facebook or Twitter etc and I certainly don't allow it be used in areas I control. They are the biggest time wasters and misinformation sources out there. After all, time is money. In general, if directors can't justify at least archiving their public twitter comments on their official company website, then we should beware.
And remember that old adage: "Don't be a fool, vulcanize your tool"
