I download HN data via API and generate Word Cloud for everyday's posts

why I did this? Because I'm trying to find a way of finding a new technology before it's popular, HackerNews is definitively the right place, so I used HN API to download all posts, and generate word cloud for each day's posts. what do you think? how did you find a new technology?

you may find the word cloud at http://bittrending.date/
