I think when the Evolution word gets out, things will be way clearer about the Evolution / Revolution distingo.
Still, my understanding was Evolution will keep an active status (e.g regular upgrades, even if incremental ones) and as such maybe we should find an alternative term to "legacy" which might have a "dead product" connotation. During the transition phase (that’s for us experienced Evo users - we need to get used to Revo before actually jumping to it), many people will keep Evolution to run their website and some might never need to make the jump. Alternatively, some people (my guess is mostly devs) will go straight to Revolution because it opens so many new doors for them
Anyway, we can be listed @mootools, can’t hurt. As long as we’re clear that templates are the tie between MODx and frontend use of mootools (and not MODx core code), which means everyone is free of choosing its js framework (I for one use jQuery). In a way, we’ll probably get listed @extJS even if people are free to build a Revolution manager with another framework (if I understand correctly this will be possible).
