The biggest challenge after a #hackathon is probably to keep the hackers engaged. When they know that their effort is appreciated, they are more likely to remain involved in our projects.
One of the projects of the Chennai hackathon is the "Random Good WP India article tool" and it is really nice to learn that the tool is now available for your use. Have a look and see if a tool like this is something for your wiki.
If there is enough interest, a tool like this can become available for the projects in the Wikis themselves.
