Mena Trott, cofounder and president of Six Apart, the blog-software company, is pregnant. There, I said it — and now, so has she . Trott blames her superstitions as a first-time mother for keeping the pregnancy a secret for so long. The lack of disclosure, though, has been uncharacteristic for Trott who, as a spokesperson for her company, has long made blogging about herself an integral part of Six Apart's publicity strategy. Six Apart's new blogging site, Vox, however, makes it easier to keep some posts limited to a small circle of readers — which is part of how Trott kept her pregnancy quiet. For a blogger, work and home life are never far apart.
