The Blogosphere is continuing to develop new 'watering holes' where bloggers can feel 'at home', the latest is Twitter. It has become 'the place' to keep in contact with friends and colleagues around the globe. You communicate via Tweets ( short 140 character messages) which you either use to instigate a conversation or to further a current discussion. As with all other Web 2.0 tools there is a way to 'know' what is going on at Twitter (ask someone), when I at first arrived at my Twitter page I thought 'Great!!!!! a bit like Second Life - I have no contacts here!!!!' , and as usual I couldn't see the point as I wasn't in any discussion at all!!!!! ( is it me???).
However Edublogger friend to the rescue, with the solution - easy add all of her friends to your page (plus add some of their friends) and 'Hey Presto' you suddenly have an interesting group of new friends (Yay) - so to anyone out there looking for a way into Twitter ( use pj23harry's friends list to create your own friendship group.
Twitter has the extra dimension of being able to use mobile phones ( hey we might just have hit upon a use for mobiles in the classroom to promote language skills ( well 140 characters does necessitate brevity!!). You can Tweet and recieve Tweets to your mobile once you set it up - freedom from the computer.
While I personally find keeping up with my Ning Social Netowork can be tedious on occasions - I have to go and find stuff!!!! Twitter as in all good aggregators brings all of my conversations to me - wherever I am (on a mobile phone or computer)..... if you haven't tried it yet - go on give it a whirl - it does become addictive though so beware ;-)
Happy Tweeting

p.s. You can also use Twitter from within Second Life - which I think makes for better communication.
