A year or so ago I thought of reading a couple of GN threads to my Mum and I think she would have enjoyed them. But now her hearing and lack of concentration make it too difficult to keep up a conversation. Sometimes I might throw in a comment I have read on GN.
She has a mathematical mind and took to the computer well. However, it was just being phased in as she retired so she never really got to use it much, except at home for accounts and letters and logging the meter readings.
She was given a new computer for her 90th birthday and sent e-mails and looked at photos which we had scanned in and, of course, played the odd game of solitaire, but she doesn't really use it any more now. Shame, because the children (my 3 DS) would love to write and send her photos.
She may have enjoyed GN but would have looked at the recipes, health news, book reviews and household information more than the chatty threads I think.
