I don't mean to come across as hostile or undermine the effort that's been invested, but I can't help but be a tad skeptical about these visualizations, especially given the fact that the author (in what might be construed as cavalier fashion) presents seemingly nebulous metrics like they are absolute matter-of-fact ("Anxiety/Confidence Ratio", "Hostility/Compassion Ratio", "Depression/Happiness Ratio").

It would certainly help if the algorithm used to compute these metrics were shared and dissected. I tend to believe that sentiment analysis is much more art than science, given how tricky and profound context can be.

To conclude, I'm not going to end this comment on a negative note. I'd much rather reserve my vitriol and caustic criticism for another thread and day and abstain from calling this an attempt at gaming HN to promote a startup.

I do this not out of a lack of indignation towards what I've just read, but because I'd like to end this seemingly hateful comment on a note that isn't bitter or negative but is instead quite the opposite (without using a single word that would help the OP's algorithm figure this out).

And with that, I throw down the gauntlet. Analyze this!
