I've been posting this blog on Twitter for more than a week. It works. If you are on Twitter you can get a feed by clicking on the link at the bottom of the left hand column of this blog. Twitter is emerging as something, I don't know what. I don't have the time to follow more than a few people.
A friend yesterday said she won't use Facebook because 'I stay in touch with friends who matter, the rest are not inadvertently left behind.'
