I created a new tool that allows you to see how positive or negative the language that any steemit account is.
It's on the same page as the word cloud. Just type in an account name and then click "Generate".
Here's mine
If you have any ideas for future features or improvements, please comment and let me know!
I use this package for the actual sentiment analysis: https://www.npmjs.com/package/sentiment
