HelenMNHQ I think you've been put in a near impossible situation by MNHQ.
I honestly think it would be better to wait until all the questions can be listed with answers from MNHQ. This is dragging on because the questions such as: Why did MNHQ do this?
Did they not realise that there would be huge concerns from some MNers over this?
Why the rush to introduce it before checking that it worked properly?
Why wasn't it excluded from all sensitive topics?
Why time it at the end of a working day (yesterday) and then leave HelenMNHQ to cope with all the resulting questions?
Is that not an awful position to put someone (who would like to keep her job) in?
are not able to be answered and it causes frustration amongst some MNers. Now....if it had been but up for discussion by MNHQ beforehand, this could have been avoided.
Bless you but tis my job although I'm whingeing.
Ok, attempt to answer your Qs (forgive me if you've already clocked these answers further up/down the thread):
Why did MNHQ do this? Because we thought it would be a good idea to allow people, if they wanted to, to have a slightly more intuitive and more familiar way to link to an MN thread they like on Facebook. More intuitive because it's next to the thread title rather than in the Viewport bar as it is now (and still is) and more familiar because those who use Facebook are used to seeing it on many, many other sites. And, yes, because it might bring some extra traffic our way (which helps pay to keep MN free to use, keep MNHQ in biscuits etc)
Did they not realise that there would be huge concerns from some MNers over this? Truthfully, no. Although we did wonder if some people might mistake it for a 'Like this post' button - which has been discussed at length on many Site Stuff threads and generally panned.
Why the rush to introduce it before checking that it worked properly? Embarrassingly, we did think it worked properly. 
Why wasn't it excluded from all sensitive topics?
It was excluded from Relationships, Bereavement, Miscarriage, OTBT, all special needs topics (including Special Educational Needs), Antenatal Tests/choices, Antenatal/Postnatal depression, Mental health, Life-limiting illness. We'd also requested it be excluded from Child/Adolescent Mental Health - but that somehow got lost in the workings. It is now excluded from there, as well as from Forces Sweethears, Fostering and Adoption.
Why time it at the end of a working day (yesterday) and then leave HelenMNHQ to cope with all the resulting questions?
Agree that it wasn't the best timing. But tis my job to cope with your questions, so I can't moan really although I probably have a bit
Is that not an awful position to put someone (who would like to keep her job) in? Not really. I can take it.
