What Not To Say

This report at the BBC on the downside of “baby blogs” is interesting. I try to be discrete about the kids, images especially. I also keep away from work related topics and a few others that spark tedious threads. Some folks here, both known and not, use pen names, which is fine, while others give only a first name and no links. On the other hand, Ian tells all or at least much and others I know discuss the kids specifically. What ought not be discussed?
