There is simply no way the information on a social media site can index, catalogue, make searchable, etc. information to the same extent or quality that a dedicated forum can. I get that FB/twitter/instagram/insert-favorite-site-here are all quite popular...but they are NOT designed for long-term information storage. No offense to those who use them, but those sites are better suited to announcing what you had for dinner last night; information that will be soon forgotten. If you want to save a detailed-write-up for how to change your kanuter valve or blinker fluid....FB simply sucks, imho.
