Nice! I really like postgres-based queues. Another one is

https://github.com/ryandotsmith/queue_classic

It uses LISTEN/NOTIFY. It might be interesting to compare it to que in the README.

I'm really interested in suggestions or comments about Que - I'm trying to make it as durable as possible while retaining its speed.

I'm also looking for a steady job using Ruby, if anyone is hiring in Seattle. My email's in my profile.

Thanks!
