I made a little program to make it easy to, given a word you want to learn, find example sentences for it on twitter. It barely works, but it’s already useful. I really like the flashcards I’ve made from twitter, they have a nice… flavor?

If it’s broken for you, let me know how and I’ll try to fix it. I’ve tested on my mac only.
