“Finally!” local Tumblr mogul Anthony de Rosa reblogged when he saw the news. It’s rather amazing that an embeddable “share this via Tumblr” button didn’t exist already–we know users have been clamoring for it, and it’s something the other major major social network start-up in this city added before it had half Tumblr’s userbase–but now it’s here, so shut up. “It’s now super easy to add a ‘Share on Tumblr‘ button to any site,” the company staff blog says. “The Tumblr Button can give you complete control over how your content appears when shared on Tumblr. Not only does this mean specifying an excerpt or summary, but also deciding whether it appears as a Link, Quote, Photo, or Video Embed.

“Even better: This can be deeply integrated with just about any publishing platform to add contextual buttons next to things like paragraphs or photos… The appearance of the button is also completely customizable.”

When asked for comment, local Tumblr moguls said, “Weee.”

Tumblr servers crashed around the time Betabeat discovered the new button and remain crashed as we type. “We’re very sorry,” the 404 page commented.
