I absolutely agree. I`m not a good writer to be honest. But bringing original, selfmade music or a video to this community should not be downvoted.. Because it's alot of work to make your own musical piece or video. And some people are just not good at writing blog posts. But this is what the community is for: To post content about music. So I don't really know if it's a big problem, when the blog post is below 300 words, when it contains original art, which took alot of time to make it.
My post about my own music was downvoted too. Well of course, sometimes it just happens, by missclicking the button or something like that. But that's kind of "frustrating", if you try to bring original art to this community.
