Also, there is not a single negative comment here. That's a HN record. Congratulations!
And yeah, I've been surprised! I hadn't anticipated so many comments about the web site, since the feature is a Javascript library. It's like going to a movie for the previews.
Definitely grateful for the feedback, though. It's great that quirks that are being constructively reported so they can be fixed.
Well, first, I think you need to accept the fact that you made a truly stand-out website, with a useful innovation (the Q&A format with code examples) that people are going to copy (and to good effec).
But second, the comments about the web 'preview' is the GCD of HN - Haskell, .Net, and Python programmers might still take a peak at a JavaScript library web page, even if they won't use it immediately.
Third, and this is most important, it would be significantly better if you published Papa Parse to the NPM registry, because then "real" javascript programmers can add it to their existing project with a simple "npm install papaparse --save". Publishing is trivial (install npm, run 'npm init', set values, then 'npm publish').
I'd love to package this thing up for NPM. But I'm not a Node.js developer, so I haven't tried running this in Node. I'll see what I can do though to make that happen.
