Note for Moderators: ExpressionEngine has a sister product called MojoMotor, which though much more lightweight, shares it's CodeIgniter DNA (and a very similar templating syntax) with EE, and allows migration to EE if you outgrow it - it could be considered a companion product - hence why I'm asking this question.
MojoMotor has a small but dedicated community, that I suspect broadly overlaps/is a subset of the EE community. Additionally many of the likely questions that relate to MM are similar in nature to those about EE. I therefore think it's worth asking should MojoMotor questions be off topic/out of scope for the EE StackExchange?
NB I think this is a different case to whether or not to allow pure HTML/CSS qns as there is much less value for the broader web-dev community in MM qns being answered on (say) SO, much more likelihood of them received a high quality answer here rather than elsewhere, and there are just not likely to be so darn many of them.
