Yes, I’ve signed up to Jaiku. For those that aren’t aware, internet presence awareness tools such as Twitter and Jaiku have been around for about 6-9 months now, providing a means to tell others on the ‘net what you’re up to, thinking, involved in etc, either via a web browser or your mobile phone. You can also sign up to view other peoples messages (“Tweets” in Twitters terminology) so you can keep track of others too.
