It sometimes seems that Techdirt spends half its time debunking bad ideas for reforming or even repealing Section 230. In fact, so many people seem to get the law wrong that Mike was moved to write a detailed post on the subject with the self-explanatory title "Hello! You've Been Referred Here Because You're Wrong About Section 230 Of The Communications Decency Act". It may be necessary (and tiresome) work rebutting all this wrongness, but it's nice for a change to be able to demonstrate precisely why Section 230 is so important. A recent court ruling provides just such an example:

On September 15th, in a victory for the Wikimedia movement and for all user-driven projects online, a Florida judge dismissed claims of defamation, invasion of privacy, and infliction of emotional distress against the Wikimedia Foundation. The judge found that Section 230 of the Communications Decency Act immunizes the Wikimedia Foundation from liability for third-party content republished on Wikipedia. In other words, Section 230 helps Wikimedia safely host the work of Wikipedia's contributors and enables the effective volunteer-led moderation of content on the projects.
