Some sites offer multiple services, and if one is not SaaSS, another may be SaaSS. For instance, the main service of Facebook is social networking, and that is not SaaSS; however, it supports third-party applications, some of which are SaaSS. Flickr's main service is distributing photos, which is not SaaSS, but it also has features for editing photos, which is SaaSS. Likewise, using Instagram to post a photo is not SaaSS, but using it to transform the photo is SaaSS.
