Much of the experience from this post i did myself too. I really whish content would metter more ...and would be curated without the need off enything than good content!
I am a guy who just like to wrote a comment when i have to say someting, not just hello im here...but this is not enough on steemit. Like you said Comunity work is so important...
I think it is fine that not only content is important. But what you do and how you behave with the community.
I think it is not in balance atm as how much SP you have pretty much determines the value of your post as well...I dont know either. I try just to enjoy the ride a bit more then I do atm
