I don't even disclose assets or income on here (or MMM or BH). Sometimes I will mention spending and WRs, so if someone really wanted to they could back into an approximate FIRE stash number. But both those numbers vary over time and have adjustments that I make to them for various reasons. I also don't think I have ever posted the two numbers at the same time.
I used to share numbers with my Dad and Mom. I stopped doing that about 10 years ago because (a) Mom didn't care, (b) it was never enough to impress Dad, and (c) I didn't want my Dad to know that much anymore.
I have started sharing some approximate numbers with my three kids as part of a long process of trying to properly prepare them for their (future, potential but probable) inheritance. Two of them don't care and are more frugal than me. The other is a spender and keenly interested, but is also showing some good character and wisdom about it lately - he seems to be slowly catching on that his siblings have money because they save it and he doesn't because he spends it all, and not having money isn't that fun.
