Social Media Marketers can now share content on even more networks from the social media managing dashboard of HootSuite, which has just launched an App Directory that allows users to add extensions to their dashboards in order to create a customized sharing experience.

The App Directory opened up with support for four popular content-sharing networks that include YouTube, Flickr, Tumblr and Get Satisfaction.

These integrations allow users to upload, search and comment on YouTube videos and Flickr photos, publish blog posts and comment or re-blog on Tumblr blog posts, as well as participate in Get Satisfaction support conversations – all through the HootSuite dashboard. However, currently these new networks are only available in an advance release to HootSuite Pro and Enterprise customers, but will be rolled out to all users in the near feature.

Furthermore, the new App Directory opens up opportunities for third-party developers to build extensions for the HootSuite platform.

“We look forward to seeing the unique extensions, mash-ups and integrations savvy developers create for the HootSuite App Directory,” says Ryan Holmes, CEO of HootSuite. “Our rapidly growing customer base is eager for more tools to spark their social-media powered campaigns and build their brands online to drive leads and awareness. If you have an idea, I encourage you to apply for access.”
