Are there any resources where you can post a variety of ideas?

Question

Computer networks

Are there any popular resources, forums, communities (preferably Russian-speaking) where you can publish various ideas for optimizing processes or objects? In principle, sometimes something comes to mind, for example, how to make seats on an airplane more comfortable with a specific implementation. It is somehow stupid to publish on your blog, because it will be left without attention. There is neither time nor desire to engage in patent search or patent. I would like to throw it somewhere where the idea can be noticed (even without profit). Or where they poke their noses that it has already been and has long been known to everyone.
