Those are pretty absurd arguments. Have you ever deployed a scalable PHP app? While it might be somewhat easy to deploy a simplest-case PHP site, real sites are much more complicated. * For good performance you need at least 2 boxes (Web Server and DB) * For scaling web to 2+ boxes, you need to deal with sessions meaningfully * For HA/Failover, you need to run a load balancer and infrastructure to keep hot-standby boxes running. In fact, the only difference between a scaled PHP app and a scaled Rails app is the ruby interpreter. Everything else pretty much you need solutions for on both languages. When Heroku first came out, I immediately asked when to expect PHP support. Since the answer was "don't expect it", I am glad to see someone else working on a solution.
