We should maybe include a "GNUnet in 5 minutes or less" on the website. The old LEGO analogy is nice, and lynX did a great comparison here: https://secushare.org/img/stack-comparison.png
We don't really need the ISO OSI model here, but even this can be added, as we've already used it throughout the years to compare to the GNUnet stack.
A short addition:
(1) various forms of onion routing are in active research.
(1.1) see for example the "big data, little data, no such data" presentation of Christian Grothoff from 2017
(2) what we are still trying to solve here, mainly, is making it harder to know the path of communication. Today, if User Lora with Node A talks to User Charly on Node B, the data goes through N nodes. The N nodes between A and B are aware of (parts of) the path, but the communication remains encrypted (in very short terms explained).
I've read into this again. 'Replacing' will be clear from context. This was added very recently (2016?) to the homepage by myself and to the official description.
The Manual (the pushed content as well as my stacks of old fashioned paper corrections) is not mentioning it. For the new website it (the description) either will be described as it is right now (unlikely) or rewritten to be easier to understand.
You are welcome to communicate feedback to our (GNUnet) mailinglists. We are in the process of replacing the website (Drupal is good, but doesn't get the job done anymore for us), so if there are problems (even if just interpretation problems or tiny things that throw you off) I invite you to send them to the appropriate mailinglist listed at https://gnunet.org/contact_information
