I'm not offended by the comment, nor do I have trouble understanding it. It's just odd to express inclusiveness by highlighting and justifying a term rather than adjusting it.
"You folks" sounds corny. No one says "folks", in my experience, other than corporate managers in emails.
It's hard for me not to write in an alive way, which means using informalities when they feel like the mot juste. Actually, I'm dreading the prospect of having to strip all possible misunderstandings out of my writing in advance. It feels like going to language jail. But I understand why people do it and why I may have to. I hope that anyone who cares about this noticed that I did replace "you guys" with "you all" above.
Edit: When I said "all possible misunderstandings", I wasn't talking about inclusivity—I meant literally all possible misunderstandings about anything.
I did the same thing myself with my general assumption that all online authors are 'he' until otherwise noted, with the excuse that it eased the 'he/she' usage issue. That annoyed the living shit out of me, as it was really an excuse for laziness, so I changed it. Now you'll usually see me refer directly to someone's handle, an article author's surname* when it's known, or just say 'the author'. Occasionally it makes the sentence feel a touch stilted, so I haven't perfected it, but I'm much happier with that than the previous way. Sometimes I use 'they', which is gaining acceptance, but there's still a group of people that can't stand the singular 'they'. Overall it was fun training myself that way.
You'll be under more scrutiny, admittedly :)
*What prompted me to do this was watching a political talking heads show. I noticed that male politicians were always referred to by surname, as were older female ones, but young female politicians got the informal first-name treatment. It really drove home the difference in professional respect given to the various groups.
(Edit: Part of why I consider clear use of "you guys" to be so limited is that when used in professional/quasi-professional tech industry contexts, it can accidentally annoyingly remind readers that we're among very few women around: http://subfictional.com/2012/07/02/language-matters-stop-usi... )
I've been a public forum moderator for two or three days at this point. I'll probably find a lot of hybrid tones to use before there's a reliably good one. Your patience in the meantime is appreciated.
