Maybe I'm old school, but I never believed the trade-off of personal information was worth the benefits of social media. (That's another discussion.)

For a source of immediate information in a crisis, I can see social media being very useful. One would have to carefully gauge the quality of that information before acting on it.

My primary grouse is that, unlike forums, content on social media is locked behind a paywall, essentially copyrighted by the platform, and can't be preserved through projects like Wayback Machine (archive.org).

So, when it comes to the accumulation of long-term knowledge and experience, they can forget it for you wholesale.
