This is a Twitter bot that tweets a word of the day from Francis Grose's 1811 Dictionary of the Vulgar Tongue.
I found the book on Project Gutenberg, and I just couldn't resist.
Basically, the bot runs as a cron job on a machine of your choice. When run, the bot will check for a word database (a collection of words and definitions, with already-posted words marked off to avoid duplication). If the database is not present, it will parse the book's text (included) and create one, then post a word. If the database is present, it will post an as-yet unused word. No words will be re-posted until the entire definitions set has been used.
That's about it. It uses a twitter api wrapper to actually post to its own account, @daily1811slang.
