Every now and then a question pops up about Media Manager, like this one What CDNs can I connect to with SDL Media Manager. Various answers/comments on this question claim the question is on topic if it is a Tridion integration, and off topic if it would be a Tridion integration.
I think we should welcome those kind of questions instead of declaring them offtopcic (link). Although SDL Media Manager could be used as a stand alone product (as in not integrated with SDL Tridion) and some questions might not be directly related with SDL Tridion CMS, the questions are still relevant for the audience and the Media Manager service is closely related to SDL Tridion.
It's like questions which could be answered without Tridion knowledge, i.e. a .NET troubleshooting question. Those questions have a weaker relationship with the main topic of the site, but we have to embrace those questions to make tridion.stackexchange an open platform where everyone is welcome, and to encourage new users to post their questions and answers.
