Hey Paul, thanks for the post. It looks like you are working solo, is that correct?<p>I would be interested in seeing a more detailed post about your stack and what your backend looks like. Maybe I missed it, but how are you processing the photo filters before you upload to facebook? You made it seem like the facebook images did not really have to touch your server. Are you processing the images on the client side and them uploading them to facebook?<p>Keep up the work, I look forward to seeing updates on your blog.
