In the last couple of weeks, there has been significant news from two WordPress competitors. Drupal lead developer Dries Buytaert has raised VC money to start a commercial company called Acquia to support Drupal, and SixApart has released an open source version of their Movable Type software dubbed MTOS. I think both are good developments for the blogging and web publishing markets. They will make more high quality products – backed by viable companies – available to satisfy the accelerating growth and needs of these markets.
Most interestingly, this also means that three of the leading blogging/personal publishing platforms are all open source now.
I’m not sure how much the success of WordPress has influenced these two developments, but they do seem to validate the path that WordPress and Automattic have taken.
