In 2006 I started NaBloPoMo as kind of a joke because I'd failed at NaNoWriMo the previous year. I decided that if I couldn't write a novel in thirty days, at the very least I could post on my blog every day for a month. I thought maybe thirty or forty people would do it with me. We ended up with around 2,000 bloggers, I think. In 2007 we moved to a real web site and got almost 6,000 people, and by January of 2010 we had more than 16,000 members. WHERE DID ALL YOU PEOPLE COME FROM?!
In 2010 Eden sold NaBloPoMo to BlogHer.com. On November 1st, 2011, the old NaBloPoMo site (hosted at Ning) was closed, and NaBloPoMo is now hosted at BlogHer.
