That's exactly what I mean -- people believe in Big Data so much these days that when something appears in a sufficient portion of search results, it must have actual validity.
Isn't that the same as natural language? "Bone Apple Tea" gets corrected both because it's wrong, and because many people know so. "Begging the Question" is used incorrectly _so frequently_ that even dictionaries have come to accept the incorrect usage as an alternative. It's now correct-ish just because it's popular.
So if Node.js has that many more hits than nodejs, it's not surprising that some people see it as canonical.
Hearing the context of this conversation, though, I can see that "nodejs" in your resume is a signal to senior peers within that community--others who are "in the know". That may be a useful filter.
As an aside, I never thought "begging the question" is used incorrectly because it is easy to tell whether or not someone is referring to the fallacy based on the context. If the meaning can be understood, then that's what matters.
