I was thinking about this today actually. While I don't think actual spam should be rewarded or even posted on steemit, I think the standards of posts should be reconsidered. For example, you mentioned one liners. Most of twitter is one liners but that doesn't mean it's spam. So, if it's an original good thought, I don't think it should be considered spam or a bad post that shouldn't be rewarded. As new users come on board and get pennies for their 1st posts, it's not really worth investing hours into one post. Most of social media that steemit is compared to like facebook and twitter runs on people sharing links and pieces of content they like they and want to share with others. That goes for reddit even though some original content is posted there. The value of steemit can be that I can share a video I like with my friends here with a short comment with my thoughts on steemit and get some money for it and get some share of that post on other social media for the benefit of steem. Others who can invest hours into good content and feel it's worth it for them can do so. I think a healthy mix of both will bring this platform balance and quality that it needs.
