If I read an article about some SQL trick and the example is in say Python and I use PHP I can reuse that without a problem because the SQL is the same.

If I read an article about some SQL trick and the example is in say Python and I use PHP then I can't reuse that without a problem – I need to know about how the Python driver works vs the PHP driver. It'd be awesome if the basics would be covered – just find() would be helpful. (Of course then there are the object mappers, hm....)
