good points, indeed i explain every day to several people, one of them is Dana Edwards who is also posting on steemit about some of the concepts that arise, and the rest is on bitcointalk and basically nowhere else for now. however note that the first alpha has nothing in common with bitcoin, except the promise to be a platform for a better coin but is just one use case, so i cant see how the bitcoin crowd vs general crowd should affect the explanations about the first alpha

to comment on the first point:


basically, the vision for later versions is that you'll have to write just clear and correct english, and you'll get suggestions, autocompletions, autocorrections, and markups of how the computer understands it, during typing. for many years such "typing tools" (call it so) are an essential tools for programmers (they put it under the name "autocomplete" but it's more than that).
three words is too restrictive to be comfortable, but it's not hard to take it from there into something more so.
indeed can compare NTriples to Turtle or Notation3, where the latters contain many useful syntactic sugar. quite technical syntax though. on tau, we'll be able to define many syntax (grammar) we like, and then using logic to define what it means to be true.
