Congratulations on taking this leap.
Although I log onto Facebook and post trivial updates sometimes, I avoid the site most of the time. In the past, I've had so many conflicts due to misunderstandings on Facebook that I decided to step back. Like you, I keep my account because I use it to keep up with businesses. I also use my Facebook account to log in to many other accounts. If it weren't for those two reasons, the account would be gone!
