About demographics - I'd say a majority of my visitors could not care less about technology and most do not have social profiles they use regularly.
However they are finding you via The Net and/or recommendations therefore IMHO I feel you require an identifiable presence, one that shows you are a significant resource for the hobby, it need not be huge, just something that shows that Sgt_Kickaxe is the place to go.
Does that make sense?
Oh, and use a pseudonym if you're as paranoid as me:-)
