Weatherall’s blog has some interesting comments on choosing a Creative Commons license for your blog, focusing on the differences between Australian and US copyright laws -

Creative Commons licenses strike me as a peculiarly American solution to a problem that we don’t necessarily have in spades here (yet). The attitude of ‘Freedom and Contract for all’ is terribly American. Yes, there is an international ‘porting’ movement, which we have seen in Australia - but what I’m saying is that the idea of this kind of license is a bit American, and we should recognise the differences between the US system and ours.

I agree with her that one of the main reasons to apply a CC license to a work is to publicise the fact that it is an issue you are thinking about, rather than seeing the licenses as a solution to copyright issues -

Why buy in to this American solution? Because it seems to give people some comfort to see my positive affirmation on the blog that people may re-use the material. In other words, I’m using it not as a legal tool, but as an indicator of attitude.

I chose an Attribution / Non-Commerical / Share-Alike license for Blisspix.net and will likely choose the same if I have the choice when publishing articles in Open Access publications in the future. Share-Alike is probably the most important aspect of the license to me, being a supporter of GPL and copyleft principles in general. In this sense, the choice of license is inherantly one of personal politics.
