As you say Prospector, we haven't signed a code of conduct, and I'm not suggesting actually writing one out. But I do think it's worth stating publicly that there are assumptions we make when we get together, which is that we are trusting each other with certain details of our personal and our financial lives, and that we hope - no, expect - that people will exercise discretion with them. Of course, we can't control what people do, but we can as a subset of the larger MMM community, make it clear what the community standards are. Just like, by posting the article here, plainjane, you're suggesting to any Toronto area lurkers that frugal one-upmanship is not part of our community standard, and subtly communicating to them that they shouldn't come to a meet-up with that attitude.
For anyone linking over to the article, you'll see the comment I made. I think he missed my point in the response, so I will post a follow-up. I'm just trying to formulate it in my mind first. The thing is that he could have told exactly the same story, not naming the city in which the meet-up took place, or which online community it related to. That would have been fine. My big issue is that he's not actually kept things as anonymous as he thinks. Anyone who read this forum can figure out who the people are, who are usually a part of that group.
(I have a secondary issue with the fact that he can't say for sure what that group is like, since he wasn't at the meet-up himself and is relying on information filtered through someone else's perceptions. But let's not go there right now.)
TL; DR - Sharing bacon and cookie reports are fine, but let's keep personal details we learn about each other to ourselves. Share people's stories with others only in ways that don't risk them being personally identified. There's a big difference in saying "I was talking to someone the other day who's trying to change careers because their industry has lots of issues," and saying "I was talking to someone at the Toronto MMM Meet-Up, who works in X industry, and is trying to change careers because of it." Remember that anyone you share with, may also share with others, and you lose control over how they tell the story. Some may even choose to share that story with the wider world. (Oh, see, I did go there after all!)
