I doubt it, the sheer volume of Facebook groups and the volume of posts to them would suggest quite the opposite.
If you look at posts here and on various blogs, many are simply the very random 'look what I did' and +1 responses that Facebook does effortlessly. Blink and they are gone, subsumed by a series of similar posts. It's almost instant gratification for the egomaniac.
What Facebook can't do is link topics in a coherent serialised narrative like the numerous project and 'build something' threads here, and their accompanying discussion.
FB is far less searchable too, try finding that half-remembered project in the FB 'stream of consciousness.
We are in a time of change, where the 'show and tell' posters are finding their niche with Facebook and the 'circle time' guys are sticking to forums. Forums that had a heavy proportion of the former have naturally suffered from this change.
We must be allowed to discuss all things about the hobby in a dignified manor and not have censorship.
'Must'? It's a private forum with a published set of rules and moderators appointed to enforce them. What you post and whether it is censored or deleted, is at the whim of the owner and his lackeys.
Thankfully our dictators have been benevolent, the rules relatively few, the members mostly self-policing and the moderators fairly laid-back.
Something to be proud of certainly, but don't mistake it for 'having rights' or 'freedom of speech'.
