It will need time for me to reply through all of those, but I will reply them all. For languages, I see every single one that you have proposed are important, but this is what we are going to do:

  1. I am going to find a plugin (needs to plug into our existing blog system) that can scale with any number of languages or translation contributions. I do not think create another a separate instance of the blog system will be ideal – it will not scale with the numbers.
  2. We are going to deploy one language at a time. Make sure the solution is stable and well organized.
  3. When time proves the point #2, we will add more and more languages for translation. So don’t worry if we haven’t add your language yet. It will be a huge community project! Let’s make it a sucessful one.
