Yea, I write "guys" a lot. I'm aware of it. And I'm looking to improve.

Some other friends use geeks to stay gender neutral. Any other suggestions?

@maloki kinda like some people use dude without using its "gender".
@Siva_Machina Yeah, I get that. But like, as someone said somewhere:
"Guys isn't gender neutral until streight-men can say 'I slept with some guys this weekend', referring to females"
@maloki I guess that would apply to dudes as well. But at least for dude. I would assume context changes the meaning. Like gay, queer or faggot(which is a good by the way).
