Other than the tight circle that is the community that we play in, we keep it VERY quiet. We own/operate two local small businesses, so it doesn't do well to have our personal business out there.
But we have discussed it a time or two with some friends locally. Takes a while to gauge just how people are going to take it, and it's not always positive. We've connected with a few local couples, though, and it's been very rewarding. It helps that there's sort of a floating "Ivory Club" night at some of the local clubs where we can meet like minded couples and singles.
