Agreed.
I don't think that it is a bad thing to keep our quality at a certain level if we want to but I don't think that should be a requirement. Sometimes I just like seeing what someone is up to even if they only posted a picture and a few words. If I like what I see, I don't feel bad spending an upvote on it even if it is just a little post.
Plus, few here are formally trained to write and we all have our own skill levels so it is a bit unfair to hold amateurs to professional standards.
