Still waiting for comment from Automattic and WordPress owner Matt Mullenweg, but some WordPress.com users take this SEC filing as a sign that the blogging company took funding.

But WordPress has never announced any funding — and, well, they seem too bright and innocent to try hiding income from the volunteers at WordPress.org. Could someone with, you know, any sort of business knowledge explain what this "registration of sale of securities" means?
