I’m using MonkehTweet for ColdFusion. I was trying to built it on a Node.js app, but the authorization token that allows users to post and see DMs rotates between users that are logged in at the same time. In other words, a user is logged in and issued an authentication token, then a second user logs in and is issued the same authentication token. I’m willing to work with either technology as long as I can get it working.
EDIT: I was also using the twitter module for Node.js. Here’s the git repo: https://github.com/desmondmorris/node-twitter
