I am leading a workshop on Monday 27 June 2011, at TOOLS 49 in Zurich on the idea of developing a worldwide New Eiffel Technology Community. The idea is that languages that survive like Java and Ruby today don't depend on the qualities of the language, but on the qualities of the 'technology stack', i.e.
As an Eiffel developer, albeit currently keeping my powder rather dry (!), I and possibly others might like to have a better idea than we have at present about how big the Eiffel community really is and, perhaps more importantly, whether it is growing, and if not why not.
A Register of users, potential users, and developers might, just might, be a useful resource.
