Slide adding one million new Flash widgets daily

Slide, the most popular widget maker in the world, says users are adding one million new Flash widgets daily across all non-Facebook social networks, such as Myspace and hi5.

The San Francisco company says it now has more than 134 million unique viewers of its widgets per month (up from 117 million in March), giving it a lead over its rival widget-makers that Comscore’s data has backed up. Growth has slowed from spring, but continues.

Slide provides create-your own online photo slideshows that you can embed in your Myspace page, and related widgets for personalizing social network pages.

Slide separately has some of the largest applications on Facebook, as measured by total number of users. Within Facebook, it has also been aggressively promoting other widgets available on Slide’s home site, Slide.com. This cross-promotion activity appears to have helped Slide see traffic growth on its home site, as we reported last month. Rockyou has done something similar.

Chief executive Max Levchin told us more about his plans for monetizing Slide in this June interview. Since then, the company has launched an ad network on Facebook.
