The Wordnik / Bot Summit Hackathon
For more information, see the website.
It runs from Friday Nov 7 until Sunday Nov 9.
Open an issue on this repo and declare your intent to participate. You may continually update the issue as you work over the course of the weekend. Feel free to post dev diaries, sample output, etc.
Also feel free to comment on other participants' issues.
The Wordnik API is well documented, but you're going to need to sign up for an API key to do anything with it.
There's an open issue where you can add resources (libraries, corpuses, APIs, techniques, etc).
