I find Facebook to be a useless format for any serious discussion. If it is an active page any post will quickly disappear off the bottom and into oblivion never to be seen again.
Their system of [comment > reply > reply to reply, etc] with paragraph indentations is absurd. You might never find the most recent post when a topic has been bumped with a concealed [reply to reply] comment to someone other than yourself.
That said, I do participate in a BionX ebike group just to garner information and find parts for a discontinued product that I have. I don't maintain a FB page with personal info.
