So don't except the premise of the questions. If I may cut and paste from the other thread:
"Why are we playing fast and loose with your privacy?"
We are not. Mumsnet, as some have said, is not private - it's anything but - I imagine we are per user the most quoted from site on the web in this country and one of the most linked to on social networks like Facebook and Twitter.
Mumsnet, as many have also rightly pointed out, is different from those networks though because we allow and encourage anonymity via nicknames and name changing. This button will not compromise that - you do not have to click on it and tell your friends that you are on Mumsnet.
Yes someone else could link to a thread that you have posted on but it's really no different to what goes on all the time anyway - you still have your anonymity in the same way that you currently do - if you are worried that you could be identified from your posts by someone outside your own facebook circle who might happen to know you from them, then that's is already an issue, I'm afraid.
