FB is a much more world wide jet experience... Its so easy to post stuff and share with so many like minded people. I'm afraid this forum is on life support. Its just effortless to post pics on FB. Manufacturers know this and are sharing stuff real time. And they will respond to you questions right away.
Don't quite get the hang up with not being on FB. It is a giant time suck for sure, but it has more new jet content in a day than we get in a month on RCU.
