Erick Schonfeld was a little off; he edited the article after a statement from the Mozilla CEO.
Mozilla has hired 3 of the principals from Humanized. They will be joining the Mozilla Labs team on January 16, 2008. We expect a lot of innovation work from them, some Firefox-related, some broader, just like everything else in Mozilla Labs. This was not an acquisition. No premium was paid and no intellectual property was acquired by Mozilla.
The work done by the Humanized principals speaks for itself -- there are lots of great, web-relevant ideas in their work and we're excited to have them join Mozilla. --Mozilla CEO John Lilly
