Don't hesitate to give us feedback - good, bad and ugly. Email openshift@redhat.com or post on the forums and we'll get right on it. Around docs, we're trying to tune the primary landing spot:

We also love involvement - good, bad and ugly as well ;)

I didn't really like dotcloud when they released their pricing info. It didn't really encourage apps that use a lot of services.

But their new beta pricing of pay per hour per unit of memory is a lot nicer.

I find the memory amounts way to fine grained. It encourages me to have as little buffer as possible. Why pay for 128megs when I can pay for 96?

Never heard of Dotcloud before, anyone have experience hosting a decent size app with them?

Wunderkit (http://wunderkit.com) runs on dotCloud. So doe Punchtab (http://punchtab.com). Both serve many millions of monthly uniques.
