One can't be a little pregnant. You can't jump off a 12 foot board and not get your head wet. AND You can't get into social networking if you are not truly ready to do so. I recently had a connection send me an email which basically stated that he and his wife were knew to social networking. His email said...
"She has mentioned to me more than once that people are posting pictures of her that she would not post herself resulting in many comments from people that she could do without."
It concluded by asking me to refrain from posting any pictures of her and thanked me for my understanding. At first, I thought, ok, no problem. The more i thought about it, the more I thought, Why would someone be on a social networking site if they didn't want to be social?
This woman was and is very attractive. The pictures were very vanilla. She and her husband were sitting in a chair at a party and smiling at the camera. There also was another one with a group of 10 people sitting on steps following a senior prom. I couldn't imagine what comments people would make about these.
Again, if people aren't ready for sharing out there, then they shouldn't step into it until they are. you would never get on stage at a karaoke bar and read poetry...or would you?
I would be careful posting photos of other people either way, if they have requested that you don't do it. I know many people who are on social networking sites that have asked me not to post certain pictures of them because they are friends with colleagues or business associates that they don't want to see them at a party or what have you. The photo might not have been the problem. perhaps another friend posted something that was worse. Either way your site is open for you to post whatever you want of you. its your networking site and if someone politely asks you not to post something I wouldn't make a big deal about it.
