I understand how you feel. Some people are obsessed with FB and spend far too much time there imo - I am somewhere in the middle and find it to be very useful for different purposes.

I have a blog and a sister FB page that I use for the blog where I post daily messages to help uplift others. I also use that page to advertise my blog to new people and gain a bigger audience for my blog and FB page, so I find it very useful to drive traffic.

I also use FB to keep abreast of distant friends' lives since they all use it, except one good friend. She refuses to get on there and feels like you do.

Then I use it to learn about local events and happenings that I may want to attend, and learn which friends of mine will also be attending that event.

But mostly, I find it indispensable for my blog and for keeping in touch with my friends.
