I kind if like the idea of embeddable rants, what do you guys think?

ColdFusion and all ColdFusion devs should be executed. Its a god-awful software from the 90's and if you still use it you're either braindead or ignorant.

Shut up about legacy CF code too! No one cares whether or not your embeddable calendar would be hard to make in JS; fucking figure it out.

I realise that CF may make things easier in the short run, but in the long run you'll have introduced so much technical debt that you'll run crying back to JS anyways; CF is so hard to refactor and even to make flexible that you would spend less total time over an application lifecycle learning JS.
