Completely agree! Facebook is too disorganised, forums have always been my preference. I must be old to lol.
It really isn't about age. It is about using the right tool for the job. Facebook is just the wrong tool for the job.
Facebook started life in 2004 as a way for Harvard students to just stay in touch socially, and share whatever was going on "at the moment". It is great for use with disposable information that will sort of appear when it gets pushed further down the list beyond the limit of users. Much like a google search that comes back with 25 pages of links, users rarely look past the first 2 pages.
vBulletin software that we are using is commercial software that came out in 2000 so it is only a bit older than Facebook. The reason you like it so much is that it was designed to do one thing...... forums. It does it well and it has wide adoption across the internet. Right tool for the job.
The version of vBulletin we are using came out in 2009, showing that it has been this durable and useful over 8 years is very good for software, though they have newer versions, probably with better security .
