Twitter Bot on Google App Engine

Over the weekend, I have started working on another application to be hosted on the Google App Engine. This application is a bot that reads from a set of RSS feeds and posts the updates to a specified twitter account.
On the face of it, this is a simple project, but there are some interesting intricacies that I wanted to put down in this post. The idea is to create a management dashboard that does the following

• Allow users to specify which twitter accounts to post to
• Twitter status update interval
• Feeds that will act as a source for status
• Interval for fetching feeds
• Multi tenancy, supporting multiple users for bot

The Google App Engine database has to be used to save the updates to handle the difference in frequency between the feed and twitter updates. Watch out this space for updates.
