I believe that the use of ANY social media has to be done with the awareness that you possibly unleash a monster that you can no longer control. Every time you hit a ‘Publish’ button you have increased your profile in cyberspace – for better or worse.
I believe that you will not do any harm to yourself or jeopardize any relationships as long as you conduct yourself professionally. If you mention any client or post a picture of anybody other than yourself, make sure it is done with their permission, also for the wording that you use.
It is my personal conviction that the social media (or blogs, even IDEA answers) need to be viewed as a window display to your business and yourself.
