Even that fairly technical document contains no formal definitions or proofs. It would also be much improved with actual mathematical notation. Again, cryptography is a subtle science. It needs proper setup, proper explanation and proper contextualisation. That's not what blogs are good for. Sure, write a blog to accompany a formal document like a paper, but don't replace one with the other. Finally, PDFs are only the most popular format for paper writing because LaTeX does not compile well to HTML, and LaTeX is the best language for mathematics.
