Would be cool if a UI like steempeak could assign an SEO value to the article based on current search term popularity ranking found in the post. Tagging @asgarth and @jarvie. :) This could be abused however by posts just listing the most popular keywords.
Ah actually would be nice if someone did a post to educate writers on how to find trending topics and keywords, I'm not even sure myself, would have to google it and wouldn't it be nice if the tutorial I found by searching was on a Steem post!
