Like RA Meyer who was composing task 42, I was pretty amazed to discover that newsgroups were still around as these electronic bulletin boards seemed a thing of the past. But they are obviously still there, if not quite getting the same use as they did before Google took off. I clicked on the Society.libraries.talk site and had a look at the usage, i.e. it was great in the early days of the internet but has decreased greatly in recent years. Surprising? I don't think so.
I then did a search in Google Groups for breast cancer and came up with 6,690,000 groups!! I hunted through a couple of the lists for their postings and wondered where a newly diagnosed person would start? Well, probably they wouldn't start with Google Groups but with Google, and the question of what he or she might find there is another one.
