I am. Sweet Pea from here got me into FB, even though I was adverse to it at the start. Through FB I now have many friends, most from the exJW community, some from JWD/N, and some just by association.
I post pretty mundane things when I feel like it, pics etc. What I love about it is I've now met about 20 people from around the world through the exJW FB connection, as well as ones I haven't met in person but have come to know through FB. Leaving JW left a gaping hole in my association, and with FB it doesn't feel quite as gaping.
I check it all through the day and sometimes have running convos, like the one right now about sake and I just had a chat with JK666. Crumpet, who I never met personally but we have mutual friends from the UK, now lives in the Maldives. I love reading her posts and seeing her pics. This would be a friendship I would miss if I didn't have FB...along with many many others.
