Each user can start blogging (images, Youtube videos). To avoid confusion, each topic / title must be available only once ("My last job at Panasonic", "when I last edited for Panasonic" etc.). This makes it possible to distinguish the subjects in different languages from each other. For maintenance, Webspace, the users pay per blog once a Euro Aufandsentschädigung, by Paypal, Sofortüberweisung. Here a clear simple billing system would be good.
The blog is then as a separate page in the page, which can sell them, if that is also more well-known. Other users can submit an offer to the author and buy this blog / page. Here it is important to have a function that tells the users that I do not deserve this process and they have to deduct the corresponding taxes themselves.
The blogs can also be called without registration, shared with Facebook, etc. Users can invite their friends via FB, Insta, Tweeter etc. to "liken" their blog themes or to start blogging topics that can be linked together. The blogs can also be commented by other users. There is no moderator who monitors the commits, but there should be a "report post" function.
At the end of the blog, the "tag" (s), which show all related posts when clicking, are shown and the advertising banners with which money is earned (vllt in the beta version, the advertisement was not included in the first version also)
Overall, it will be a blog with a domain on which, however, all topics are clearly separated from each other.
