That said, my own coding is currently leaning toward Node.js for server stuff. I'm using Neo4j for data and it turns problems right on their ear - for my space (not all spaces), it's a million times better than relational and a thousand times better than document databases. So I'm looking for languages/frameworks that make my particular use of Neo4j more graceful. Started with Rails, but gave it up as the ActiveRecord ORM is kind of Neo4j-hostile in practice. I expect this is true of most ORM solutions (hence the R, for "relational"), so maybe I can make it better in a lighter-weight system.
At any rate, there are no silver bullets, but plenty of wooden ones. I lump PHP in that category. If there's an existing PHP app, then by all means maintain it, but don't use it for new projects!
