I think the massive layoffs at Verve might be a reason for not "tending to" the official site that much. I was sorry to hear about that, especially at this time of year.
However, I really don't think it would hurt to put an announcement and link to the press release on the entry page of the
www.dianakrall.com website. I do understand a certain need for privacy, but on the other hand, births, deaths and marriages are also a matter of public record. I don't think it's prying to acknowledge those facts of life. And I think it lends a website credibility when it has the official information on its site in a timely fashion. Otherwise, people, who are naturally curious, might start to seek out less credible sources of information -- which, as a rule, you want to avoid. I was in PR full time for five years, and one of our goals was to keep people coming to us for information because they knew they would get a credible and timely reply when people sought information about our business. That's how you keep down rumors. I don't think excessive prying is called for...just an acknowledgement of the births and a link posted on the website. (Of course, as a fan, I'd like to know more, but that's not what I'm suggesting here right now.)
Personally, I'm really looking forward to when Diana and Elvis feel comfortable with a cute photo of the babies and the new family. But I'm sure all the parents on this website know how you felt taking care of one baby at a time. You're bleary eyed, lucky to get three hours of straight sleep and an uninterrupted shower. So I think the cute photo can wait!
