This document by Michael Everson is particularly revealing and in the end damning to his whole attempt at disunification of the Northwest Semitic script.
I am not interested in participating in this kind of discourse. This is not "Michael Everson vs the Semitic scholars", Mr Snyder.
Your "Northwest Semitic" is the same as "my" Phoenician in any case; so, in fact, you agree with the Roadmap as regards some points.
Lumpers can use Hebrew. Splitters need more granularity. We will, eventually, be investigating the levels of granularity that will be useful.
