That might be so Di, but for those of us not on FB there is a feeling of being left out of the loop.
It's not a deal breaker, please don't think that, but it does grate at times.
If the FB crowd have conversations, that's fine, but it would be better if they stayed on FB and not leak out into VV.
Imagine it the other way round and a closed group on VV was posting views on FB to which others had no way of responding.
