Show HN: App that suggests Amazon products.

I've built an app that suggests Amazon products after you've provided your Twitter username. It fetches all your tweets and calculates the tf-idf of the last tweet.

URL: suggester.me

Something similar was built by a HN member a while ago, but I've contacted him and he told me he was no longer working on it, so I decided to build my own.

Feedback would be greatly appreciated.

EDIT: Forgot to mention, the username needs to be without the "@".
