#redis Matt Stancliff talks about the challenges on a large open source project.

Redis is a popular key-value store used by many companies. Matt Stancliff, a Redis Core Contributor, talks about the challenges with working on a large open source project. Takes your 30 minutes, but worth it.

Update:
At first I must say that Matt is a bit prejudiced about MongoDb. but still a "must watch" video if you are interested in open source development and redis.
