Thanks for writing this, Sandro.

Of course, I understand that there are different skills at different 
levels and people are not necessarily checking everything. I was never 
assuming that everyone is willing to check the dirty details. But my 
assumption is that the people who are interested in the matter of a 
specific question (like Pat and I are for the semantics, like Eric, Andy 
and Gavin are for the Turtle grammar) will spend the effort to 
understand the technicalities, and they'll manage.
That's what I meant: we all have the capacities to understand the 
details of what we are interested in, when we decide to spend the effort 
(at least that's what I presume).

But my point was actually to say that you can't avoid putting the 
technical details with the excuse that most people won't read them. You 
can't avoid putting the grammar in place, even if only 3 or 4 people are 
going to read it through. You can't define a formal semantics with 
"just" English sentences.
That's the important message, sorry if it was awkwardly formulated.
