Have just taken what feels a major leap and set up a Twitter account! Have always had vaguely anti-Twitter feeling, but looks a little more interesting than I at first thought. Can see that if you sign up to a lot of other tweets you could suffer from information overload though!
Subscribed to CPD23 RSS feed, so will be interesting to see how everyone else is getting on with things. Feel as if I've got a little behind with being off work for a week, so madly trying to catch up now (in between boxing stuff up for the imminent library move).
Pushnote to me perhaps looks the least interesting option of the three, but am sure I shall have a closer look at some point.
