It's regrettable you're not getting the feedback you should be getting, as this is something that will really help you stick to it. On the other hand, the very reason you aren't getting feedback is a good one: you're working on obscure articles, which is precisely the area wikipedia needs work done on in order to become the fully-fledged, echt encyclopedia (as I'm sure you know in the case of proprietary equivalents professionals are hired to fulfill the role you are fulfilling). Anyway, consider yourself a lonely pioneer ;)
