I find that it's an excellent idea and I added the banner to this blog but... how does it apply to the rest of the world? I mean, I'm Italian, my site is in Italy, part of the work I do is in Italian. The intent of the licenses is very clear (I did not try to read the legalese version) so I could expect anyone to understand how I would like the content of this site to be used, but I think that copyright laws might slightly differ from country to country.

Remember, this is the web, there are no borders. Any "bloggin'lawyer" who could shed some light on this issue out there?
