So I apologize in advance that I'm going to totally swamp this little thread, but it'll show people what it actually means to be creative to make something happen. I'd usually do this in FreeMind or my journal.
Feel free to add anything, ask any questions...
So I did a Google search on "save the world"
And now the question becomes, did any of those websites/projects actually get anywhere? What results did they achieve? Why were they effective or ineffective?
