MongoHQ public beta Heroku addon

Last year I tried to talk a customer into using Heroku for a medium size web deployment. They didn't go for it, and so we spent a fair bit of money setting up Elastic Load Balancing, EC2s, etc. Unless you expect a zillion users, it just does not make sense to spend the effort on custom deployments. Same positive comment for using high quality VPS hosting where you can expect your hosting company to do frequent incremental backups, proactively repair RAIDs, get VPS instances back on line quickly after hardware failures, etc.
It is a lot of fun setting up servers but the question is whether that is worth being pulled away from application development. Anyway, good news re: MongoHQ being an add-on product.
but, i still wonder how heroku works as a startup from a more engineer perspective, for example, how to get things moving as fast as possible. maybe an engineering related blog like what twitter or facebook have might help.
offtopic: when heroku is going to launch in other regions especially Amazon EC2 just launched in Singapore?
