THANK YOU for your posts on this topic. You've inspired me to finally pull the plug on Facebook, something that I've been considering doing for months and months.
I too don't like Facebook. I never did. And the thought of spending an hour or two per day on Facebook to promote my site is not something I want to do. Time is money, and Facebook offers little in return. And, as you say, life is short.
I unpublished my solar site's Facebook page over a year ago, and I deactivated its Commenting while retaining the Like buttons in Face It. I decided to drop the Commenting feature since it mostly attracted the unwanted self-promotion of vendors and affiliate sites, so there weren't many valid comments anyway.
The larger recipe site is another matter. I retained its Facebook Page up until today. After checking on GA, I discovered that only a tiny fraction of Sessions arrived from the site's Facebook Page, as most arrived from visitor's Facebook pages, and I'll still be getting those in any event, whenever visitors share my site pages. I would have retained its Commenting since the comments have been complimentary, but without the ability to reply to new comments except through a personal Facebook page, I decided against it. More time saved.
I felt a huge RELIEF the moment I clicked that "Unpublish" button! My only regret is the time I wasted up to then.
Wishing you much success,
