Brilliant Ideas That Will Never Work: childfree ring

This idea started here and was enhanced by this.

Childfree people don't want to be in a relationship with non-childfree people, and vice versa. There's just no point. However, reproductive goals don't always naturally come up in conversation, and it's really presumptuous and kind of creepy to bring them up early on in a potential relationship. ("Want to go for coffee sometime?" "Sure, but I won't bear your children.") This could have the unfortunate result of people ending up emotionally attached to people who would make unsuitable partners. You might be well on your way to falling in love before you discover that one of you wants kids and the other doesn't, so the relationship will necessarily have to end.

Solution: a universally agreed-upon visual signal denoting one's childfree status. It would work the same as a wedding ring. You wear it and anyone who cares can look for it, see that you're childfree, and proceed accordingly. It doesn't necessarily have to be a ring, but it should be subtle, visible, and unisex.

The flaw in this plan is that since a childfree ring is worn only for the benefit of potential mates, wearing one implies that you're on the prowl. After all, if you're in a relationship, the general public doesn't need to know that you're childfree - whether you're CF or not, you still won't bear their children. Not everyone might want to walk around at all times wearing a symbol indicating that they're on the market. (I certainly wouldn't!) But then if you don't wear it all the time, you'll have a romantic comedy meet-cute with the guy in front of you in line at the grocery store and fall in love before you both discover that you're CF and he wants 12 kids. So I wouldn't wear it (although I'd have supermarket guy reading my blog before we got too serious anyway), and if not everyone wears it then it won't work.

Actually, now that I think about it, people who are in the market for a relationship should all blog. Not about looking for a relationship, but about everyday stuff. If I were looking for a relationship and a potential partner read my blog, they'd discover that I'm CF and urbanist and recovering catholic, they'd get a sense of my politics and tastes and neuroses and sense of humour, so any core incompatibilities would be identified immediately and incompatible partners could reject me before I even noticed they were looking. It would be much more efficient.
