I moved this to a new thread, as it was getting off topic in the original thread, and I think there may be some mileage in discussion of this as a separate topic.
We definitely have a male dominated IT industry, certainly in the UK. At work I look at who's sitting at the desks, and in the whole office there are one or two women doing development, or project management jobs. This has been the case for many years, but wasn't always the case. Back in the early days of computing, it was the other way around, with women in programming and IT support roles.
I don't know why this is, clearly women are just as capable in technical roles as men, probably more so. But there doesn't appear to be the interest in schools. By the time we get to university stage, it's almost all men doing those computer science degree courses.
In the UK we have something called "STEM" (Science, Technology, Engineering, Maths), which engages companies to go into schools and promote technical subjects to all children. There appears to be more emphasis on coding in schools, so maybe we'll see a turnaround, in terms of the number of girls who get interested in IT subjects.
So the point is, I suppose people here are assumed to be male, especially if it's not specified in the member profile. But I quite often stop myself from using the collective term "guys", or "dudes", and substitute it with "folks", because I know that certainly the staff team is not all male. But people can react differently. Some women would just accept the general term, when referring to a group of mainly men.
