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 "peeps" is a good choice, but I really don't think "guys" is gender-specific anymore in that context.
@ocdtrekkie guys isn't going to be gender neutral until straight men say "I flirted with / slept with some guys this weekend".
