Hey all,
Just posted on the new Universal Edit button functionality to the Wikimedia Blog. http://blog.wikimedia.org/2008/06/19/firefox-3-and-the-wiki-edit-button/
The developers are doing their best to publicize the extension. I've pinged out to a few reporters. I think the broader angle is 'edit' as a browsing function becoming as common as read/subscribe/respond. The other great angle is how much, and how well (imho) wikis collaborate on tech development. And increasingly I think we'll be able to gang a lot of resources and energy towards PR collaboration.
If you've got the extension and like it, blog about it! Let's get the word out to more bloggers and media.
