From the Blogger Blog:
Shortly after Blogger launched photo uploading two years ago, one of our engineers whipped up a web page that would show us the pictures that were being uploaded in real time. The result was fun, often beautiful, but above all, compelling. We couldn’t stop watching.
Over the years we’ve kept this photo scroller as part of the Blogger offices, on a monitor or projector, as an interesting (distracting?) slideshow, and a reminder of the diversity and vivaciousness of Blogger blogs. The fame of the scroller spread within Google, until one day we were asked, “so, when are you launching this?”
“Um…,” we replied. But we knew a good idea when we heard one. We got our UI people to come up with buttons and fadey effects and we got our engineers to make the whole thing fast and robust. A bit of work later, and now we can share it with all of you:
Blogger Play will show you a never-ending stream of images that were just uploaded to public Blogger blogs. You can click the image to be taken directly to the blog post it was uploaded to, or click “show info” to see an overlay with the post title, a snippet of the body, and some profile information about the blogger who uploaded it. We also wrote a Blogger Play FAQ with more information.
