Great Question @reiseamateur. There are so many new tribes pooping up indeed. Right now I think it's pretty exciting as there is something extra for everyone to earn in a variety of niches. I do think better explanations of each platform should be summarised at a central point so everyone knows which coin pertains to a specific interest. Which will help with the too many cooks problem!
It's definitely given something extra to the platform and is pretty exciting. Come on, its raining coins! who's going to complain!
