I have been having fun with PMOG ( passively multiplayer on-line game) over the last two years or so. It is not quite a game more a fun take on what I spend my time looking at on the web - it is more fun than i-Google history.
There is quite an interesting debate on the public/private face of web2 developing on John Connell's blog. Creepy treehouse could be a goth band ( probably is). It is really all about being appropriate in your conduct and communications. As a learner I would find it creepy if the school wanted my mobile phone number - I'd need a pretty good explanation and maybe even some bribe before I'd let this space be invaded by learning or worse .. teachers.. The mobile learning brigade would not endorse this.- though nobody has ever explained to me who pays for the texts or web phones ?
Though I have to say both as a pupil and a teacher I witnessed some "creepy treehouse" conduct long before the advent of the web. There is some really sensible ethics emerging in this debate around both engaging learners and the yawning digital divide which is still there.
Worth a look before you add your entire address list to that new web2 application that you really like or invite lots of folk to manipulate some on-line system that they don't understand.
Every one has rights and the Creepy TreeHouse isn't just in learner space.
