Hey bookworm, if you're already looking for your next read, the answer lies in your tweets. BookRx is a book prescription engine that analyzes hashtags, accounts followed, and words used frequently to create custom reading suggestions.
Just enter in a Twitter handle, and BookRX will match the account to six or seven different subjects of interest, offering the top-selling and most iconic books in each category.
The web app isn't perfect (it thought #pizza was most directly related to science and technology), but it's a neat artificial intelligence experiment by Northwestern University's Knight Lab. Give it a try and tell us — what do your tweets say about your reading preferences?
