Dear All,
My two pennies about it from Polish perspective.
I do not like Facebook, I fully understand its conflict with my concept of freedom and I have been fighting with a need of having an account till 2014, when some other reasons forced me to do so.
However, facts are as follows. Polish usenet group pl.rec.radio.amatorskie is currently an uninhabited island. Although Polish usenet is in quite good condition (opposite to opinions in another thread), only electronic group (pl.rec.elektronika) is alive among topics similar to radio. There are several foras with some ham discussion, but the activity is very limited there.
On the contrary, the FB group for Polish hams has currently more than 2000 subscribers (when there are similar number of active licenses and even taking into the account that not every member is a ham, there are majority of hams here) and the discussion is so alive, that I am not able to read everything even logging every day.
So, what to do? There is no chance to advise 2000 people to move anywhere else. So I simply browse this group to be up-to-date. The same situation is with several other hobbies I am involved in.
This post is not an advise to create FB group (as I also think its a bad idea as this will split discussion to several places), nor any advise to make an FB account. But in many cases FB cannot be simply ignored.
