I don't think it's unorthodox. Perhaps uncommon these days. The application logic needs to live somewhere. I like doing in stored procedures because you are close to the data and that leaves your client code free to just implement the user interface. It's much easier to support different client platforms without having to rewrite all your core transactions. It's actually my favorite way to architect an application. I like views for the same reason, especially for use with 3rd party reporting/BI tools.
