While it isn't always evident in my public posts - I have a potty mouth so I'm not going to chastise others for having the occassional word slip out. Dang, in my book, isn't a swear word and I'm fairly sure I use "damn" quite a bit. I'd say used in moderation, unless I start getting complaints (and to date, I never have) I see no problem. We are (mostly) grownups around here after all.
If you prefer to walk the fine line you can always do what some of us have done in the past which is use the asterisk to self censor. In other words, if you want to F-bomb then just say F**k or F***ing heck. etc ... But this isn't a requirement.
Opinions? I open this to the group for discussion
