Everyone has their own way of doing things. I don't doubt that you are very open....I've sensed that in some of your discussions in hereMy 'extreme' openness with my clients is part of my (for lack of a better term) 'schtick'. It's kind of how I present myself and my business. Of course, I've had 1 or 2 in the past who have made me question this method, but overall, it's been great! The FB page is an excellent tool, whether your personal one or a business dedicated. I just find it easier to maintain the one page and if the parents are cool with it, then so am I. Besides, they see me in an unprofessional light fairly regularly....such as this Friday night when we go to a 'Parents' Dinner' possibly to be followed by a pub crawl
As long as I'm professional when I need to be, they don't mind....though my atmosphere isn't for everyone. It draws exactly the clientele I want.
Good luck sorting out your decision. I think you'll find the additional advertising to be beneficial.
