Could people please not use this list to announce information of no particular interest to the people on the list? Hundreds of thousands of babies are born every day. While the whole phenomenon is menacing, one of them by itself is not newsworthy. Nor is it a difficult achievement--even some fish can do it. (Now, if you were a seahorse, it would be more interesting, since it would be the male that gave birth.)
Following your example, I might send the list an announcement whenever a new GNU program is written. That happens less often than babies are born, it does the world a lot more good, it reflects more conscious creativity and hard work, and some of the readers might actually find the information useful. Even so, I think most of the readers would consider this outside the scope and purpose of the list. Clearly that goes double for babies.
Of course, we have another place for announcements of new GNU programs. If some people like to read birth announcements, perhaps you should set up a suitable list or newsgroup. Perhaps rec.births? (While you're at it, start rec.deaths for obituaries--they're usually more interesting to read.)
These birth announcements also spread the myth that having a baby is something to be proud of, which fuels natalist pressure, which leads to pollution, extinction of wildlife, poverty, and ultimately mass starvation.
Perhaps the people who have decided to have no children should start making proud announcements, so as to set a better example. I could start. I'm sure everyone on this list will be glad to know I don't plan to reproduce myself.
