As we know magento is an E-commerce platform and user might ask related questions. I can only one new proposed site in stackexchange is directly related to E-commerce. Should we not classify such question as off topic until E-commerce launch?
Good question! I think this is exactly the kind of thing we're going to have to iron out here in order to make this site truly useful and tailored to the Magento world.
I would say that if it does not relate directly to Magento in some way, it shouldn't be allowed. So for example a question like:
I don't think should be allowed. Although we all care a lot about eCommerce, I think part of the reason we should be strict with this is that opening up this site to all things Magento (merchant-facing, developer-facing, marketing-facing) already casts a pretty wide net, so we'll need to be careful not to dilute it too much.
