This seems highly dependent on which kinds of software companies you are talking about. I hire lots of developers and I have never looked at anyone's github profile. Also, I don't recall any candidate asking me to look at their profile. I have seen a few resumes that have included one, but not very many - and I look at a lot of resumes. I'm not making any judgement about the value of the profile, but in my corner of the world it doesn't seem very important or even common.
